Hi everyone, I've got a fun one here I hope one of you enlightened souls can
help me with.
I am experiencing an intermittent performance problem with the
javax.xml.transform.Transformer.transform(src, res) call. I am using xalan
2.4.1.
- When I run a specific transformation job (exact files data every time) in
my development environment (Windows2000, Weblogic 7.1) it always takes
approximately 15 seconds.
- When I run this same job in our test and production environments
(Solaris, Weblogic 7.1) it normally takes 15 seconds but sometimes takes
between 15 and 27 minutes to run.
- Sometimes if I restart the Weblogic server instance I am deploying to,
the job will go back to taking 15 seconds.
- When the job appears to be hung, there are plenty of threads and plenty
of RAM available according to the Weblogic console.
I included a thread dump below from one of the Solaris boxes that was taken
while the job was hanging in hopes one of you can make more sense of it than
I can.
Any insight or suggestions would be appreciated.
