Re: Process names not showing up and lsof reports nothing

Hi,

	we are running on osx 10.2 and 10.3 (mixed) with Java 1.4.1
and wo 5.2.2. Site has very much traffic (200-400 concurrent sessions
at 20 min session timeout with around 10 instances). I've wotaskd
running under Java 1.3.1 and it doesn't have the too many open
files problem...

To determine the process id since lsof is not very reliable sometimes,
modify the SpawnOfWotaskd.sh script like (a tip from my coworker):

===  Go to appropriate dir
# cd
/opt/Apple52/Library/WebObjects/JavaApplications/wotaskd.woa/Contents/ 
Resources/

=== Original file (Apple)
# cat SpawnOfWotaskd.sh.bak
#!/bin/sh

$@ 1>/dev/null 2>&1 &

=== Modified by me  (not the best choice of files)
# cat SpawnOfWotaskd.sh
#!/bin/sh

$@ 1>>/var/log/woapplication.log 2>>/var/log/woapplication.err &

You will find the startup messages inside the webobjects.log.
They contain the pid and the port number and a matching
should be possible....
