Swap space looks like this:
total used free shared buffers cached
Mem: 8306064 6183208 2122856 0 60492 5620972
-/+ buffers/cache: 501744 7804320
Swap: 4096532 656 4095876
Thanks for the link. The “Troubleshooting and Diagnostic Guide” seems to be full of information but it’s getting a little bit late for this hardcore java action (and a new episode of “Californication” will be aired in half an hour ;)).
I almost forgot: There was an older trunk version of GeoServer 1.7 (with the GeoSearch module) and GeoWebCache running in Tomcat.

Betreff: Re: [Geoserver-users] Apache Tomcat crashing…Hi Stefan,
I found this:
The next improvement is visible when the system is almost out of swap
space and an allocation from the native heap fails in the VM. In that
case the VM aborts and you get a one-line error such as the following:Exception java.lang.OutOfMemoryError: requested 16 bytes
for CHeapObj-new. Out of swap space?This message has been known to confuse a lot of developers. At first
glance it might it might look like that the java heap is
full. Of course
if you increase the size of the heap with the -mx option it
might make
the problem worse as the larger java heap means there is less native
memory available.from:
http://blogs.sun.com/alanb/entry/outofmemoryerror_looks_a_bit_betterI don’t know whether it will help but maybe you can give it a
try. Could
there really be problems with the swap space? You’d better check it.

Hi
after running Apache Tomcat for a whole month without problems, it
crashes now too often (after approx. 2 days). The error I get:
“java.lang.OutOfMemoryError: requested 140 bytes for
CHeapObj-new. Out
of swap space?”My JVM options:
export MALLOC_CHECK_=0
JAVA_OPTS=“-Djava.awt.headless=true”
JAVA_OPTS=“$JAVA_OPTS -server "
JAVA_OPTS=”$JAVA_OPTS -XX:SoftRefLRUPolicyMSPerMB=36000 "
JAVA_OPTS=“$JAVA_OPTS -Xms128m -Xmx768m "
JAVA_OPTS=”$JAVA_OPTS -XX:PermSize=128m "
JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=256m "Is there a way to find out which process makes Tomcat crashing? (I
have two other servlets running in Tomcat) And how to avoid
crashing
Tomcat this often? [GeoServer 1.6.4b, Apache Tomcat 5.5.25 on a Red
Hat Enterprise Linux ES release 4 (Nahant Update 6)]regards
