yossi reginiano commented on GEODE-5224:
----------------------------------------
thanks for your reply Anilkumar Gingade
the scenario Is as followed-
create entries in certain region that should be picked up by some process - and
creating backlog and eviction by not triggering that process
letting it run and create 2-3 CRF files
then bring up the process that starts processing the records - we then notice
that statistics is not calculated correctly and entriesOnlyOnDisk does not
decrease to 0 , while entriesInVM decrease beneath 0
*do note that the issue is only in the statistics - and the real entries are
processed correctly*
our configuration is as followed -
<disk-store name="PWInfo-overflow" allow-force-compaction="true"
auto-compact="true"
compaction-threshold="50" max-oplog-size="256"
queue-size="4096" time-interval="1000"
write-buffer-size="32768">
<disk-dirs>
<disk-dir dir-size="40960">data/.</disk-dir>
</disk-dirs>
</disk-store>
<region name="PWINFO_1">
<region-attributes concurrency-checks-enabled="false"
data-policy="partition"
disk-store-name="PWInfo-overflow" disk-synchronous="true">
<partition-attributes startup-recovery-delay="60000"
redundant-copies="1"
total-num-buckets="${cc:TC/IMDG/gemfire_pwinfo_sum_num_of_buckets:-113}"/>
<eviction-attributes>
<lru-entry-count maximum="2000"
action="overflow-to-disk"/>
</eviction-attributes>
</region-attributes>
<index name="PartitionIDIndex" from-clause="/PWINFO_1.keySet e"
expression="e.PartitionID"/>
<index name="FuncIndex" from-clause="/PWINFO_1.keySet e"
expression="e.Index"/>
</region>

> Key: GEODE-5224
> URL: https://issues.apache.org/jira/browse/GEODE-5224
> Project: Geode
> Issue Type: Bug
> Components: eviction
> Reporter: yossi reginiano
> Priority: Major
> Attachments: EntriesInVM.png, EntriesOnlyOnDisk.png
>
>
> we are using geode 1.4 and facing the following issue
> after getting into eviction we can see that entriesOnlyOnDisk is shown
> correctly, the problem is when getting out of eviction - we can see that the
> summarize is getting messed up and that entriesOnlyOnDisk is not reduced to 0
> but rather stay high and on the other end - entriesInVM is reduced under 0.
> the numbers sum up ok - the issue is only that we reduce too much from
> entriesInVM while part of it should have been removed from entriesOnlyOnDisk.
> the issue can be reproduced very simply by getting into and out of eviction
> and monitoring the statistics.
> please see following screen shots that describes the issue-
