Hi,
The node just stopped.
In our test the issue is being reproduced whenever the producer continuously
PUTs into the region, consumer stops GET and stops delete entries from the
region.
In a while, as long as eviction rate goes up, the exception occurs. We tested
with GEODE 1.2.
Here is the region definition:
<region name="EXTERNAL_RECORDS_1">
<region-attributes concurrency-checks-enabled="false"
data-policy="partition" disk-store-name="ExternalRecord-overflow"
disk-synchronous="false">
<partition-attributes startup-recovery-delay="60000"
redundant-copies="1" colocated-with="PWINFO_1" total-num-buckets="251"/>
<eviction-attributes>
<lru-entry-count maximum="200000"
action="overflow-to-disk"/>
</eviction-attributes>
</region-attributes>
<index name="ERPartitionIDIndex"
from-clause="/EXTERNAL_RECORDS_1.entrySet e" expression="e.key.PartitionID"/>
<index name="ERFuncIndex"
from-clause="/EXTERNAL_RECORDS_1.entrySet e" expression="e.key.Index"/>
</region>
Thanks

Subject: Re: DiskStore exception while region data evicted
Hi Gregory,
Is the node stopped and restarted? If so how many times?
It looks like the evict operation freed up 2401bytes...But at that time the
current bucket size (as per stats) is (2401 -1425 =) 976bytes...Since the
updated bucket memory stat was -ve, the system thrown exception...
If you have reproducible scenario, can you send it across...Or steps to
reproduce...
Can you send your cache xml (or region configuration). And logs and stats if
possible.
-Anil.

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:
