Hi Rainer, seems we have still an issue in jvm config. we have not noticed the concurrent mode gc failures that led to tomcat overload and bad responses.
14896.148: [Full GC 14896.148: [CMS (concurrent mode failure): 1102956K->326641K(2359296K), 4.0684463 secs] 1280549K->326641K(3067136K), [CMS Perm : 131071K->62120K(131072K)], 4.0690589 secs] 15346.161: [Full GC 15346.161: [CMS (concurrent mode failure): 1546160K->324956K(2359296K), 3.4321099 secs] 1637284K->324956K(3067136K), [CMS Perm : 131071K->62222K(131072K)], 3.4327402 secs] Unfortunetely the concurrent algorithms in java need itself 30%-50% of memory, so if the jvm still allocates the objs in tenured and there is not enough memory for concurrent gc stuff - it makes stop-the-world. Anyway these events are fired in JVM and would be really really nice if the load-balancer could be smart enough to react on it , e.g. redirecting the load. Agreed, that this problem is not easy to solve and may be requires some features from jvm side that are not implemented yet.
