Thread problem
Hi all
My Ofbiz is extremely slow - the following error log seems to point to it.
"A web application appears to have started a thread named [ThreadPool-0] but
has failed to stop it. This is very likely to create a memory leak."
Shutting ofbiz down does not take this away - ofbiz wants to complete this
every time from startup onwards. Is there a way to manually remove this. I
checked Thread List in Webtools app but it only lists threads with no option
to remove them.
Any pointers
Gavin

Hi Gavin,
You shall go through the Apache OFBiz Technical Production Setup Guideover here ,
Setting up ServerStats.properties and Cache.properties will tune it fine,even though apart from this you shall
check for the entries in JobSandbox Entity,In case you have multiple entries marked as 'SERVICE_PENDING'
for services with the same name, that could also be a cause to slow it down.
Regards
Prince

That message is a warning. Is it happening on shutdown? If so, that is normal. There is a shutdown hook missing somewhere that no one has bothered to fix. During operation (i.e. everything up to shutdown) this is not a problem, and my guess about the chances that this is causing a performance problem is approximately zero.
Have you tried a profiler to see what is really slowing down your app?
Also, have you tried basic performance settings like the cache properties and such?
