Are you doing that? If you aren't, then your OOME is coming from somewhere else. Do you get any message at all along with the "OutOfMemoryError" -- the JVM will usually say "PermGen" or "Heap" or something else. The best way I've found to detect OOME is to use the - -XX:OnOutOfMemoryError flag for the JVM. I have no idea how that will (or will not) work on an AS/400. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJTMeATAAoJEBzwKT+lPKRY4FcQAIB6uHKVkekznRZxrveDB5UC cmiYVp6amP2/itlWRC4zS5/hv+qOzEvnwPRhFgSmip72zXQrEfZd2vEIrUh/KjSq NVsuqazz4Ws97SSdEG+sENQ1LBoeYQJQjSHJ18fGrz3Ob7zfkUwsu63nc1Z+Frmg b5tZwM2c3wTvwJKr2bUEWjzubuTsxIQWnnmdSqbvrdJ7kCtS1zbz+QCD+q5NR49I fp6yDIJCtdN7TRds9QIQRDmejKbjJi6BRPP/G4MUUMNu/9bAdLwzc8LtvH6y/cYD kleMwjcgo1VJ5hSiwo9LgD/3jTSDNUy42pMx4TIdJAkEEP3W7IroHegFoXwyL8Aw XUEOiRgFCTkjkhqCP6Vh8ez0hSM1ZAxtFWeiDEWkZ4r7b3+VKqy3d+tYjkiD7TVp FFH5XUqkHQaNwNMB9Dt3PY7IKqAmRN25d61YKb+wqaXGBRyJye9t6yk1lASlMhZB MPS9O070YV6pVw7AyBDXfGJVITI29cBhEA6fr3nUDVi4F253pZGNWxuNaO2oBkVr rj4zgIdAC46Yatnu8vl9SDxTNeQBzKMKAxs76qArXwGD0xZYlo1VeDrDfFWbU0Qe D0kjx91s2SITC095rKX06ya48CeCKnwl6hz5sqtUHqolifozCEBdIfT38R381PWU UFm8OYSaVrBCNiEdT5fN =GFO7 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
