Hi,
In our production enviroment I have a weird problem and I am trying to
understand if / how can it be fixed.
The error is like above:
*
*
*INFO: Maximum number of threads (250) created for connector with address
null and port 8080*
*

*# A fatal error has been detected by the Java
I am on something right now like this.
While running, Do a:
netstat -n grep [your port number] | grep CALL_WAIT
See if you are hung in CALL+WAIT status.

Hi,
The command:
netstat -n grep 8080 | grep CALL_WAIT
gives me nothing, yet when I update CALL_WAIT with TIME_WAIT I can see them.
netstat -n grep 8080 | grep TIME_WAIT
P.S: Just restarted the servers. As expected the thread counts dropped to
normal. Now I am on 43 Current and 20 Busy.
TIME_WAIT is fine. Not an issue. That just means they are ready to take
requests. CALL_WAIT is not good, if they stick around.
If this is an OOM error, then have you started this server and attached
javaVisualVM onto it to see what the threads and memory are doing?

Oops. You are correct. I have been up for 2 weeks on this and need to sleep.
But that was my issue.

Looks like you have two separate problems. The first is that your
Tomcat-configured threads get stuck

You can force it by:

No, that gets you a Java heap dump, not a thread dump - not of interest here.

Hi,
I probably wont be able to get the one close to crash but the jstack.out in
the attached file contains the output while the applicaction is receiving
requests.
Hope it will be more helpful.

Don't see anything wrong with the Tomcat threads. As Chris noted, they are all
just waiting for another request to show up, which is normal
