This is my java config:

No problems so far.

At MIT, we've done some adjusting of our memory configuration but have
still seen this occurring on a regular basis (from once every other
day to multiple times in one day). We currently have a band-aid in
place in the form of our monitoring system detecting the state and
restarting Tomcat to clear the issue, but are still looking for the
root cause.
Could anyone seeing this issue list how they have their XMLUI webapp
configured in Tomcat? There are many possible causes for a
white-screen in Tomcat (even outside of DSpace installations), one of
which is the absence of a ROOT webapp (though this condition is
typically permanent until resolved, but I'm looking for strange
configuration problems, so...). Here is how we have our Tomcat
configured:
- No ROOT directory in the tomcat/webapps directory
- tomcat/conf/server.xml configured with the following entry:
<Engine name="Catalina" defaultHost="dspace.mit.edu
<http://dspace.mit.edu>">
<Host name="dspace.mit.edu <http://dspace.mit.edu>"
appBase="/path/to/dspace.mit.edu/deploy/location/webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
I am wondering if doing things in this way, or a particular
configuration related to it, is causing something to hang up
occasionally. We are running Tomcat 6.0.20 through Apache2 via mod_jk.
The more details from the community on this one, the better. It's a
mysterious one. Thanks everyone!

Phil Fenstermacher commented on DS-605:
---------------------------------------
I was having the same issue and found that a different startup script
for Tomcat fixed the problem. The script that would cause the
behavior used the arguments Xss and Xmn, however after they were
removed things started behaving correctly.
The presence of the arguments I'm sure is not what caused Tomcat to
crash but rather improper values set within those arguments. If I
find better values to use I'll be sure to post them.
