This only occurs when the last client shuts down. If no data is being lost, then I would just consider this noise. You can reproduce this with EhcachePounder. Start 3 nodes, turn up the speed, then after a while terminate each serially.

Maybe a better error message?

Tim Eck 2011-05-16

just speculating really but this looks like more of a generic problem with the async stuff in the toolkit as opposed to something specific to ehcache

Alexander Snaps 2011-06-28

Yes, more on this here : DEV-5924

Fiona OShea 2011-09-26

Please also merge to ehcache-core-2.4.x and ehcache-core-2.4.6-RC


Alexander Snaps 2011-09-27

Merged to toolkit os tc-3.53 & tc-3.5.4 branches
