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:
