OutOfMemory in POI call stack
Hi,
we're having a lot of trouble in production with Solr (which is using
tika to extract contents of docs,xls, etc which in turn uses POI)
running on tomcat and OutOfMemory issue. We're been looking at this
now for a long time, we've been upgrading to the latest versions of
all jars where possible but we're still seeing this all the time in
the logs:

No matter how much perm space we assign we always run out.
I'm wondering if anyone here as any idea what could be the cause or
how we might solve this?
Any pointers would be much appreciated as I'm totally stuck on this.
thanks

That doesn't explicitly increase the permgen size though. One of the
uses of permgen is for storing classes (there's some good docs around on
the different memory regions in Java if you've not come across this
before). When doing OOXML processing with POI, and especially if you're
using the full ooxml-schemas file, you have a lot of classes. If your
permgen is too small (and especially if you have lots of classes of your
own too), they won't all fit. Try explicitly increasing the size of your
permgen

Hi Yegor,
thanks for replying. Its running on tomcat 7.0.22. Sun java 1.6 on solaris
-Xmx1024m -server -verbose:gc -XX:+HeapDumpOnOutOfMemoryError\
-XX:HeapDumpPath=/export/home/
Hmm thats odd I thought we had already increased the size of permgen.
It seems we have not. It looks like its been applied to the wrong
instances of tomcat (we run a few).
We cannot reproduce locally at all and I know it doesn't give you
anything to go on - sorry about this. I'll get the correct settings
applied and take it from there. I just wanted to see if this jogged
anyones memory ie high us of String interns, classes created on the
fly etc
Sorry to waist your time at the moment

Re: OutOfMemory in POI call stack
Posted by Yegor Kozlov <ye...@dinom.ru>.
What are the JVM settings? Version of JDK? Are you running Solr in
Jetty or Tomcat ?
Does the error happen repeatedly on the same documents ? Can you
reproduce it in a isolated environment ? It would be helpful if we can
reproduce it on the POI side.
I assume you increased perm space via -XX:MaxPermSize and
-XX:MaxPermGen. What were these settings ?
If your JVm uses CMS garbage collector you may want to try these hints:
-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
