Huge memory consumption of Eclipse Infocenter [message #475233] Tue, 10 March 2009 15:11 Go to next message

Hi,

I'm struggling with large memory consumption of Eclipse Infocenter. We
have a Infocenter library with 6 books, containing 12 000 pages
altogether. There are 4 million hits / 34 000 visits per month.

Allocated memory to eclipse is -vmargs -Xmx1536m (out of 4GB total in
server), but it is still running out of memory:

java.lang.OutOfMemoryError: Java heap space

Operating system is Red Hat Enterprise Linux ES release 4, eclipse package
version 3.4 and help plugin
org.eclipse.help.base_3.3.101.M20080728_34x.jar

Can it be true that standalone Infocenter really requires over 1536M
memory? Is there any recommended value?

For me it also seems that there might be some memory leak since the memory
consumption slightly grows until the maximum is reached (takes 24 hours or
so).

One thing that I found is setting locales (-nl en -locales en), but
testing didn't provide too convincing results.

I'd appreciate any help. Thanks!

It should not require that much memory. Setting the locales should help
the situation because otherwise a search index will be built for every
locale used by clients of the infocenter. Based on your description of
the number of hits it does sound like a leak, I'm not aware of any other
infocenter with that many users. Do you have access to any tools that
you can hook up to your infocenter such as YourKit which you could use
to measure the memory use?

Hi There

I think i'm having the same problem with my standalone Infocenter as you. Java is using too much memory then IC is stops displaying.
Did you manage to find the answer for it?

Thanks
