Hi all,
Thanks all for your responses. I will get jmap running and see what that
reports. We restart Apache nightly because it uses huge amounts of memory
because of Oracle client connections and I wonder if this is similar.
Either way Apache doesn't actually crash (it just keeps growing its memory
footprint) whereas Geoserver does and it sometimes does it more than once
per day which suggests that restarting it nightly isn't going to resolve
the problem.
The Java startup params we're using are:
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=512
# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=4096
which I only recently upped. They were set to half that before. That to
me seems like a lot of RAM to grant something that serves a very small
number of requests (probably no more than a few thousand tiles per day)

Hi Tom,
We have a fairly similar setup (Windows server pointing at Oracle) but I've
never seen that, though we do restart GeoServer nightly; might you want to
try that?
Also, what are the JAVA parameters you're using at startup (the ones that
set the memory).
Oh, and if you increase the logging level to Geotools-Developers, what do
the logs say then when this is evidenced?
Cheers,
Jonathan
