tomcat pauses then crashes after a period of time 2006-12-10 - By David Wood

Hi everyone,
I have set up tomcat to run as a daemon using jsvc, which is working well,
except when tomcat is idle for a period of time (usually overnight), and I
execute a web service client, tomcat receives the request then simply stops.
I can then restart and use it as normal. The log messages say it is
pausing, but then nothing else is reported, eg:
Dec 8, 2006 4:21:03 PM org.apache.catalina.storeconfig.StoreLoader  load
INFO: Find registry server-registry.xml at classpath resource
Dec 8, 2006 4:21:03 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 5188 ms
Dec 11, 2006 9:16:06 AM org.apache.coyote.http11.Http11BaseProtocol pause
INFO: Pausing Coyote HTTP/1.1 on http-8080 (See http://ttp-8080.ora-code.com)
Then it just crashes (eg Catalina no longer appears in the process list and
connections are refused).
I am running tomcat 5.5.20 and java 1.5 on redhat enterprise 4.
I thought this might be a configuration (perhaps timeout) option, but cannot
find any such option in the server.xml or other configuration files. I have
read the doco, which suggests using the environment variable
LD_ASSUME_KERNEL, but on further investigation I decided not to do this as
my version of java is later than 1.4. There are other posts in this mailing
list referring to the same problem, but none with a solution, although one
does think it might be a memory issue. A web search reveals other similar
problems with no solutions. I have attached some links at the bottom with
threads I have found.
Does anyone know why tomcat is stopping?
Many thanks,
Dave
