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. Dont
try an tell me youve 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
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 hadnt
been much help. So in posting the same error again I hope to raise user
sympathy ;] please help!
Sincerely,
Brendon Maragia

You can use green threads instead of native threads and thou shall see just
one process. :-)

This is how Linux shows kernel threads; nothing to be alarmed about. There
is only one process.

Hi,
maybe the many processes are because jdk1.2 and up use native threads
(AFAIK, 1.1 used "green" threads, i. e. a threading package implemented
in java itself).
With 1.2+, every java thread is a native OS thread and therefor gets
listed by ps. Have you tried forcing java to use green threads? I'm
quite sure that it is possible (RTFM).

Go to the Tomcat User's Guide:
http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/index.html
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.
Thanks,
