You should look into these if you are having too-many-connection problems. I would also look at what your application is doing during those connections. Are the connections using keep-alive? Are they being left open when after they are no longer being used? You've really given us no information except to assert that all your memory is used. I don't see any evidence that your memory is exhausted. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkfn24wACgkQ9CaO5/Lv0PD4NwCeOyPmOONqAtGQ4nrxYa0/Cx62 P94AoK6R8GbCDajRqHg7kFs6tIybtM/7 =KwVg -----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]
