In Tomcat clustering, there's away to add a listener to a channel, and get notifications based on different scenarios such as member join, member leave etc. Axis2 tribes registers a such listener in Tomcat, in order to identify whether a new member is joined/left a Tomcat channel. We are using EC2 based clustering environment, In this case, intermittently, we've seen that the member-disappear event of that particular listener hasn't been triggered when a member leaves a tomcat channel. Any Idea ?? /Jasintha -- *Thanks & Regards Jasintha Dasanayake * * * * *mobile +94 (0)71 624 1368 , -- *Thanks & Regards Jasintha Dasanayake * *WSO2 Inc * * *mobile +94 (0)71 624 1368 , --089e013cbdc480464904e32d16cb--
