Updated to version 4.2.3 some days ago and now i have high cpu load again…the exact same symptoms i had in 3.9.3 and many more reported in versions under 3.10 here:
Had to revert to Openfire 4.0.2…no problems now…definetly a problem with version 4.2.3
This seems to be connection related…
Spikes occur when a user connects or disconnects to openfire
In the morning and in the evening when people connect/disconnect the cpu spikes up to 350% for quite some time
In the nigth cpu goes down to 0% ( easier to observe the spikes )
The machine serves openfire and 2 sites (with no significant load)
here are some logs that i take from the server nohup_1.out (235.9 KB) nohup_2.out (317.9 KB)
1st log has 3 dumps in 10 minutes…cpu was high( 100-300%)
2nd log has 5 dumps
dump1 - evening after restart (restarting makes cpu go 100-300% for 10-15m)
dump2 - 10-15m later (0-100%)
dump3 - morning (100-300%)
dump4 - after lunch (100-300%) ending with Exception “GC overhead limit exceeded”
dump5 - after restart
