Subject [Jmeter Wiki] Update of "RobinWilson" by RobinWilson
Date Mon, 19 Dec 2011 16:48:23 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Jmeter Wiki" for change notification.

The "RobinWilson" page has been changed by RobinWilson:

   * MySQL DB Server (receives JDBC connections from Tomcat Server only)
+ ==== Root Cause: ====
+  * The 'iptables' service (Linux Firewall) on the Apache Server had been enabled
+  * Even though no packets were filtered, parsing all incoming packets slowed the network
interface down to the point of filling the buffers - causing a backoff period
+  * Disabling the 'iptables' service solved the problem. Command 'service iptables stop'
was issued, as well as 'chkconfig iptables off' (to permanently disable service on reboot).
