My guess is that the number of connections coming from httpd and the number of connections allowed to Tomcat don't match up. How many web servers? How many back-end Tomcats? Which connector are you using? If w = # of httpd instances c = # of total httpd threads then you need w * c connections allowed in all of your Tomcats (see <Connector> attribute maxConnections. Another possibility is that the connection timeouts on httpd (mod_jk connect_timeout, in ms) versus Tomcat (<Connector> connectionTimeout, in ms) are not the same. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJV52BfAAoJEBzwKT+lPKRYPKkP/AlnFjGxvPJPyjw3vhjDowiZ NS2vKKQZiQfzW/xqn30cbE3HJheC+7vL+ErhqCBlehZmuoFngaLiT5fpR2cPvwaM XdKB5xa7HJ/vOIBqY2vLwM0cYuqAMgYHP+MFpwGJyi3ezoyf0cn+D78y9HPJIOta K04BrKm5ZRlxMqtuCeGdP/hdT59H8X+S2XLzJ5oug8090TCHqDOmnz+tzR9BDe6o c0GgzdXTs+EweGgaq57V9dNaZl/GnrMkkDDhqS2AyEPhG7kjVKELQ0Rx2cbSGvLG EoAincsN3tMNx5vG/ZfHLf93qwB2jfqCMVnedMg7urOTtDDH8aDFhuixDxzUhHwL iulppCeeMEy8UpQV5KOLeqcww+OXZz+uLHPhP+vvqBMVhBt6Sxh1JlckqthBb3KH fc1rztloe+iw9ehVFX1654/zgVKkj77FtNZcc4bU+KGYoQmIb1fdGSfNBTTd6OTS eU1IHkb0GTsUkMa4/RZn9WhQ6r+ya8ZZL0RqtZB3nZgOr3tY2dO/aXFTu01S1meR 8wUvPEN/0bYgKMjV4qCWnpYEUdw8K9FmAphqEQThzy+4NlhfUDG7vvg+LqvTkAzt gS1S3pV6LPK2fBjKUbShLwJW3dCvEGu016oMiLHEpwBFVEC8WWl7sIV3SgZXqNZP 1k/PoTnoLV3KFsBhKKbr =lCAl -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
