Hi Christopher, Yes, we were on jdk 1.4 and now we have moved to 1.6. After this, we were facing the BufferOverFlow on this particular page so we increased the buffer size to 4 MB ( yes .. 4 MiB).
There is no increase in the number of users. The heap space is set to 128 MB, and Max Perm is set to 64mb.

Please advise. Has anything else changed recently? The only time we ever got OOMEs was when we had actually reached a user threshold where we simply needed more memory to handle the traffic. Before then, we were running with a 64MiB heap and decided to double it. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1HMpUACgkQ9CaO5/Lv0PD8HQCglFOFd17edClwYNin4DhlHV2t nJ0AoJOM3tnTuNJbQlHGECx4T7v2r39e =Jyfq -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
