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:

We get lots ( all vary slightly) but there are always in the POI call stack:

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
