Dear all,

after updating our server to Tomcat 5.0.24 last night I got 2 crashes with 
the last words

Exception in thread "CompilerThread1" java.lang.OutOfMemoryError: 
requested 32760 bytes for ChunkPool::allocate. Out of swap space?

from Tomcat. Now the interesting is that according to our GC logs Java did 
not really run out of memory. Also I checked the system's state some 
minutes before the last crash and I remember the java process having 
allocated about 270 MB and as I set -Xmx1024m this also makes be believe 
that it did not really run of the memory. The pointer to the swap space 
also doesn't seem to lead into the right direction since the machine has 
4 GB physical memory and another 4 GB swap space and nearly no swap space 
is actually in use.

So my question is, is there any new configuration parameter I my have 
overlooked since 5.0.19 or has the default value of some related 
parameter changed which could cause this error?

What makes the problem even more mysterious is the fact that both 
exceptions occurred in "CompilerThread1" but since all our JSPs have been 
compiled already and none of them has changed, I wonder why this thread 
had anything to do at all.


Best regards,
Stefan
