Hello,
I'm seeing my app die occasionally, and was wondering what is
the best way to go about investigating this. I assume from log
files, but there is a lot of old information out there so it's
difficult to figure out what is out of date and what is not. Is
there a log file somewhere I can start from (e.g. does "touch
Webobjects.log in the /tmp directory still work?). I just need
something to get me started here.
That works, but it won't do you any good. :-) That is the woadaptor
log. You want your app's log. The path for this is configured in
JavaMonitor.
If by die you mean the process stops, the most likely cause is
OutOfMemory.
If by die you mean it stops responding, deadlock is the most likely
cause. Get a thread dump when it locks to diagnose that.
