Hi all. A newbie here. If I'm posting to the wrong place, please point
me in the right direction. Thanks.
Our environment:
Jahia 5.0.3
WebSphere App Server (WAS) 6.0.2.23
Red Hat Linux ES 4
32-bit
4 GB memory
jvm 1538 MB
jahia.properties:
maxParallelProcessings = 200
pageGenerationWaitTime = 60000
suggestedRetryTimeAfterTimeout = 60
pageGenerationWaitTimeOnStartup = 10000
suggestedRetryTimeAfterTimeoutOnStartup = 15
WAS Web Container thread pool max threads is set to 400.
We're getting lots of 503 server overloaded errors at times. I'd like
to be able to increase the jvm above 1538 MB, but we're restricted to
that at the moment because of other apps running on the machine. We're
preparing a 12 GB, 64-bit server but it'll be a week or two until it's
ready.
In the meantime, how do I reduce the 503 server overloaded problems? Is
it just a matter of increasing maxParallelProcessings?
Here's an example of an entry in the app server logs. I had set the
logging level of root in log4j.xml to "info" instead of "error" for a
time to get this info.
