Subject: DiskStore exception while region data evicted
Hi team,
One of the grid members went down and entire cache is closed whenever Partition
region got an LRU threshold and overflow to disk is started:
<lru-entry-count maximum="200000" action="overflow-to-disk"/>
Disk-store defined with 40GB.
Actual metrics while crashed: entries on disk 700000, bytes only on disk ~1GB.
There is much room in the File system.
Can you help to understand the following exception:
