Tomcat shuts down automatically

Question

I\'m using Apache and Tomcat on a Windows server and since this morning, Tomcat stops working without any logs. It doesn\'t hang, it just shut down.
There\'s no log in T

Answer 1

Faced this issue recently.

Scenario : Tomcat started successfully but automatically gets shut down after 1 hour and sometimes this happened after 1 day and nothing is there in tomcat logs.

Issue : Actual issue was high memory usage and no free SWAP memory.

How I found the solution

If tomcat don't show any logs, then there must be something in system logs so, I checked /var/log/messages but since permission denied for me I tried /var/log/dmesg and got this

"Out of memory: Kill process 14606 (java) score 106 or sacrifice child".

In the output I noticed Swap Memory free 0 K. Ran top command to confirm the same. So, somehow there was a high memory usage which caused the OS to kill my tomcat process.

After spending hours finally got the reason.

ps -ef | grep tomcat showed that there were several tomcat processes running for the same application. It seems that, earlier tomcat shutdowns might not have taken successfully and the processes were not killed even after the shutdown due to some reason, which was causing the high memory usage.

So, killed all running tomcat processes using kill. SWAP memory got freed.

Started tomcat again, worked fine. :)

Answer 2

I had this problem, and I found the cause at this link. My script to start tomcat had last line tail -f catalina.out. Sometime I did not kill this script, the shell then timed out and killed the script with all child processes, including tomcat.

Answer 3

I noticed CATALINA_OPTS in my path and that was set for a lower JVM size. Hence, the crash and no log trace of tomcat was found. The server automatically shutdown in less than 2 hrs.

check, CATALINA_OPTS or JAVA_OPTS -- these might have jvm settings. either increase them or comment them out and increase the swap memory.

Answer 4

This sounds like the JVM is crashing. Have you looked for a JVM crash log? It typically has a name like hs_err_pid*.log and is created in the JVM's working directory.

If you find a file like this and upload it, then we can probably help more.

Some questions:

• Have you recently changed the version of Java you are using?
• What is the exact version of Tomcat you are using?
• Are you using Tomcat Native (the Apache Portable Runtime)?

Answer 5

another possibility is that some process was started this morning on the box that is binding to a port that your server requires.

Answer 6

“The Service on local computer started and then stopped ,Some services stop automatically if there are not in use by other services or programs.”

I gone through the problem i have tried so many ways to get out of the problem finally i got the solution as follows.

1) Click Run Command from start button.

2) Enter Services.msc then click OK,you will get all the services in your computer.

3) Select your service and right click on the service and select Properties

4) Goto Logon Properties and select Local System Account then click OK.

This will work.
