Tomcat 7 shows almost every day service temporalily unavailable at the same time

Good morning friends. In recent times, almost every day the server is showing the error service temporarily unavailable message and I just restart tomcat and the applications normalize. Apparently, this problem always presents itself at the same time, three o'clock in the morning. Early in the morning I looked at the tomcat log on the server and these errors appeared in the log. I would be very grateful if anyone knows what it could be. Because it wasn't me who set up this server and I'm a little lost.
GRAVE: The web application [] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal#5a346e8f]) and a value of type [java.lang.Class] (value [class oracle.sql.AnyDataFactory]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

It looks like you have a process that is trying to bounce Tomcat in the middle of the night. Evidence:
You have a message in the log saying The web application [] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal#5a346e8f]) and a value of type [java.lang.Class] (value [class oracle.sql.AnyDataFactory]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. This message is shown during application shut-down, and application shut-downs are typically performed when the server is being shut-down.
You have a message in the log saying java.net.BindException: Address already in use. This message is shown during container startup.
If your Tomcat restart process does not wait for Tomcat to completely shut-down before trying to start another instance, you may end up in a state where the new process fails to bind to the port (and therefore will not be listening for requests) and then the old process shuts-down, freeing-up the port. You now have a service that isn't reachable.
I would recommend a few things:
Reconsider nightly restarts. Why are you doing them? If you have bugs, fix them instead of restarting the service all the time to mitigate those bugs.
Check your restart process to ensure that the old process stops completely before starting the new process.

Address Bind exception in Tomcat

We are running Java 8 web application in Apache Tomcat 8.0.36 server since 1 year.
From past few days sometimes when we restart the Tomcat server , the application is not working. Logs are showing address bind exception for Https port.
I tried checking the process associated with the port using below command in cmd:
netstat -aon | findstr [port]
but it is not showing any process associated with the port.
I have tried closing tomcat process from task manager and also tried executing tomact shutdown.bat and then started tomcat again but nothing helped.
If the system is restarted where application is deployed the issue gets resolved but we can't restart the system anytime
Please help what could be the issue and what else can be checked?
Below is the error in tomcat error log:

See the update below. We think we have found the root cause and a solution
We have the same problem: A tomcat service that was operating without problems for nearly a year was not able to bind to the port which it used after it was stopped and then restarted.
We usually stop and restart our tomcat service regularly every night, and it used to work without problems. The problem first occurred on July 24th, so after a lot of research that I and our IT have done, I suspect that some kind of change in our IT infrastructure that happened shortly before July 24th causes this problem.
Our server is a Windows Server 2012 R2, 64 Bit, but our IT environment is virtualized, running on vSphere Host Version 6. On what server/infrastructure is your tomcat operating? Is it a virtualized system or is it running on a physical server?
In my opinion, the problem came in either with the last installed patches for Windows
(KB4338815 and/or KB4339093) or with some Hypervisor updates. But our IT is still researching.
For the moment as a workaround we do a server restart when we shutdown the service
and restart it regularly every night. But because the problem does not reliable occur on
each and every shutdown/restart, we restart the server only if it is really necessary. To achieve this we use a listener we have implemented and configured in the server.xml that scans the stderr.log just after the tomcat service has started. If it detects, that a Bind Exception occurs it restarts the server (tomcat service is installed as automatic). If you find the cause of this problem, please post it here, as I will, if I or our IT will find it.
Update August 7th:
We think we have found the root cause. Obviously the Windows Monthly Quality Rollup for July introduced this problem. In our case (Windows Server 2012 R2, 64 Bit) the problematic update was KB4338815 (see https://support.microsoft.com/en-us/help/4338815/windows-81-update-kb4338815).
If you do a quick research on the internet, the problem, which also affects Windows IIS Webserver and MS SQL Server is mostly described as related to KB4338818 (see https://support.microsoft.com/en-us/help/4338818/windows-7-update-kb4338818) but this is the same kind of update for Windows Server 2008 R2 and Windows 7.
Microsoft is already aware of the problem and describes it in its documentation for KB4338815 and KB4338818 in the "Known issues in this update" section of the mentioned articles. Microsoft states that the problem is resolved in KB4338831 (for Windows Server 2012 R2, Windows 8.1) and KB4338821 (for Windows Server 2008 R2, Windows 7)
In our case we installed hot fix KB4345424 (see https://support.microsoft.com/en-us/help/4345424/improvements-and-fixes-windows-8-1-and-server-2012-r2), also available from Microsoft, which addresses this bug and as far as we see, the problem does not exist anymore.

Connection timmed out when accessing Tomcat web manager

I installed tomcat8 on a amazon ubuntu server from a windows computer using an online tutorial as a guide.
It started from command line, a message stated it was really running, but when I try to access the webapp, I get connection timmed out.
I went through a lot of possible online solutions, so I edited my tomcat-users.xml, my server.xml, but I dont get to load the app when I enter http://server_ip:8080
When I try localhost:8080 I get access denied.
How can I verify what is wrong, please?
Oh, I also added tomcat user, group and exported catalina path.
I'm really new to ubuntu, could you guys help me? Obrigada
this is what i get from catalina.out

The thing is, Im not using these ports anymore, I changed them in server.xml file to port 80.

What actually worked for me was opening 8080 port on aws. As simple as that haha :)

Tomcat on centOS Address already in use

I get this exception in tomcat once in a day, at a fixed time, which leads to a 503 error in Apache
I looked for anything running on 8080, but none was found. I used the following commands as root :
netstat -an |grep "8080"
and
lsof -i :8080
Both returned nothing.
If I shutdown and start tomcat again, it will be fine again for sometime before this error occurs again.
I know this issue has been raised multiple times, but nothing solves it for my case.
Here are the exceptions from catalina.out for HTTP and AJP connectors :-

Error : Failed to initialize end point associated with ProtocolHandler ["http-apr-8080"]

I am trying to do external SSO in Alfresco. Done configuratoin in share-config-custom.xml and updated alfrsco-global.properties. Trying to open user dashboard by clicking on a link (URL appended with the alfresco ticket) from another application. Created a Special SSO filter to get the ticket and to set the alfTicket parameter in the connector session.

Why this error is coming?
After clicking on the link from another application, i could see that my filter is executing, but SSO not happened.

I have tried with changing the port number 8080 initially assigned. Change the same by doing the following steps:
Edit server.xml present in folder conf/ :
Replace the code below -
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
with code:
<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
Then try running. This worked for me.
