That depends on the memory requirements of your web app. When your JVM starts acting like this, try to use jmap or another tool to take a look at the heap to see what's taking up so much room. | it only uses 50mb RAM 0mb Swap without tomcat running. | There is only one client that sends 3 documents at any one time to | the service that then annotates it and sends it back Anyone got any | ideas? Im coming to the end of my tether here? Thanks Do you use sessions? How long is your session timeout? How much stuff do you put into the session? How about any other caches in your application? ThreadLocals? I doubt that the BrokenPipeException is the cause of the memory problems, but it's possible that it's a symptom of a server that is struggling to serve requests with low memory. I've seen JVMs thrash a bit when under low memory conditions, but they usually suffer from OOMEs shortly after that. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkg20d8ACgkQ9CaO5/Lv0PAv6QCfeT3zlgcL4r+aBONuD//405mz d4QAn254MoB/pVoePotUV+M18bv/85yy =EwFa -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
