Doc Type: Bug Fix
Doc Text:
<classname>AsyncCacheWriter</classname> could drop updates if it was unable to write <literal>modificationQueueSize</literal> entries within the <parameter>shutdownTimeout</parameter>, as older changes overwrote newer ones in the back-end store. This issue was primarily caused by a large queue size or a slow back-end store with a relatively small <classname>AsyncStore</classname> <parameter>shutdownTimeout</parameter> (25 seconds by default). Now <classname>AsyncStore</classname> will write everything to the backing store before shutting down, and the <parameter>shutdownTimeout</parameter> has been removed. This issue is resolved as of Red Hat JBoss Data Grid 6.5.1.

Description Dan Berindei 2015-06-24 07:09:18 UTC
When the backing store is slow and it cannot write modificationQueueSize entries in shutdownTimeout milliseconds, AsyncCacheWriter can drop updates or issue them in the wrong order.
