Konstantin,
Yes, it was started using startup.sh in tomcat/bin and used the same ports
(8080, 8443, 443) as the tomcat that died. The fact that the OS did not
recover the memory implied to me (could be wrong, even very wrong) that the
JVM just died. However, as you point out, how did the ports get freed up.
So, now it looks more like I am somehow killing Tomcat because that is the
only way those ports could be freed. Shouldn't I see some tracks in one of
Tomcat's logs then?
Thanks,
Carl

Peter and Andy,
Thanks for your quick responses.
Memory: Physical - $GB
Used - 2.4GB to 3.0 GB (according to top... have never seen it
above 3GB)
Swap - 19GB, none ever used (or, at least I have never seen
any used.)
The above are all from top.
The 2.4GB is after the JVM just crashed (after running less than an hour
after having run for five days with nary a blip) and I just restarted
Tomcat
(customers are running right now) so it is a little higher than normal
because it has perhaps .5GB+ unrecovered from the point at which the JVM
crashed.
You started the new Tomcat instance using the same port numbers that
were used by the old one?
If so, the old one has really died, but how come that the memory was not
freed?
I checked dmsg but saw nothing that looked out of the ordinary.
dmesg they say
In OOM killer scenario it can be sometimes caused by some maintenance
task scheduled with cron. But an OOM killer which does not free memory
would be very much useless.
Best regards,
Konstantin Kolinko
