Chris, Yes the stack trace was taken on server. Anyway thanks for your valuable replies, I will continue my research in this direction. Since tomcat is out of picture now, I will concentrate on my external Process or any redesign that might be required. I will share my findings, if hopefully I am able to crack this one.

If so, this has nothing whatsoever to do with Tomcat. This is a problem with your web application making a connection to an outside service that is taking a long time to respond. Set your timeouts appropriately and you won't have this stuck thread anymore. But you will have to handle error situations, of course. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAla588EACgkQ9CaO5/Lv0PBRGQCfR9Loo2m5rvQSmva7BYTar7JQ 8fUAn1uKghqYKTjbKE99ahnxGtlTaWza =Vip6 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org _____________ The information contained in this message is proprietary and/or confidential.
