Dear Chris, Tomcat crashes means, the free memory starts declining dramatically to zero, and server stops responding to new requests. I am sure with little modifications, this can be handled in code itself, and this is not a concern at all.
I am more interested in knowing whether there exists any configuration for such cases, which stops processing after some predefined time-out. I know that this can be done for KEEPALIVE requests. What @ requests in SERVICE stage. The screenshot for Tomcat Manager is attached for the same.

As others have said, without attempting to send data to the client, you can't know that they have disappeared. :( My question is why your code causes a "crash" when the client disappears, but works just fine when the client gets a proper response. That suggests a mismanagement of resources by your webapp. You might consider reviewing your code to find out why your "loss of free heap memory" is occurring, because Tomcat surely isn't causing that to happen. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAksZh0sACgkQ9CaO5/Lv0PBGfwCfVjYr8P9A0iFm6hLKkG7gxKx6 zsoAn2s5Box8os9g0dE6uFgB4TXJWPdr =ssOC -----END PGP SIGNATURE-----
