Re: to many tomcat processes!! AAH!!

Go to the Tomcat User's Guide:
 
 
and do a search for "max_threads". You can configure your PoolTCPConnectors for ajp12 and ajp13 via the server.xml file.
 
BE CAREFUL. If you set these values too low, you will undoubtedly hamper performance. However, you shouldn't leave these at the default values once you understand what they do. In my case, I am using ajp13 in all of my code. ajp12, as far as I know, is only being used for startup/shutdown of Tomcat itself. So, I cut the values way back for ajp12 and increased the defaults for ajp13.

Subject: to many tomcat processes!! AAH!!

Dear Readers,

 

I finally!!! Got Jakarta Tomcat vhosting with Cocoon and it was so so beautiful and sweet, I jumped around the room screaming in joy.  Don’t try an tell me you’ve never done that.  Anyways, I was using jdk1.1.3 ;] ewww, I know.  So I upgraded to j2sdk1.3 and fired everything back up.  Low and behold when running ps –aux, I was confronted with this….

 

root      2806 44.5  4.1 76632 10580 pts/1   S    20:01   0:01 /usr/local/jdk1.2.2/bin/i386/native_threads/java -Dtomcat.home=/usr/l

root      2844  0.0  4.1 76632 10580 pts/1   S    20:01   0:00 /usr/local/jdk1.2.2/bin/i386/native_threads/java -Dtomcat.home=/usr/l

root      2845  0.0  4.1 76632 10580 pts/1   S    20:01   0:00 /usr/local/jdk1.2.2/bin/i386/native_threads/java -Dtomcat.home=/usr/l

Not just that about 50 more.  In total about 54 Jakarta Tomcat processes, all this right after I upgraded to j2sdk1.3.  I tried downgrading again to jdk1.2.2, no dice same error.  I searched through the mail archives and noticed a guy buy the name of Pete Wright had posted a similar error.  I emailed him and he told me the list hadn’t been much help.  So in posting the same error again I hope to raise user sympathy ;]  please help!

 

Sincerely,

Brendon Maragia
