Operating Systems Solaris decipher pstack with problem lwp Post 48528 by hosierdm on Tuesday 9th of March 2004 05:18:21 PM
Old 03-09-2004
Sorry if I wasn't very clear...I was just trying not to be too verbose. JBoss is a J2EE application server. The pstack is from the JBoss server process. The database locks are coming from java code that we have written and which is running on the JBoss application server. The number of locked rows coincides with the number of CPU hogging lwps (feels like infinite loop to me). My assumption was that the offending lwp in the pstack represents something going on in the code that we have written. So I was hoping that anyone could give me insight into the pstack that I attached that could help me try to figure out where to look for problems in our code. The problem isn't reproducible and happens (seemingly) randomly...otherwise it would probably be easy to figure out without needing to dig into this stuff.

Thanks for the reply. If you can't help, no problem...nobody else has been able to help either. Smilie
