[jira] [Created] (IGNITE-5150) Allocated memory pages count is
incorrect during load test
Ksenia Rybakova created IGNITE-5150:
---------------------------------------
Summary: Allocated memory pages count is incorrect during load test
Key: IGNITE-5150
URL: https://issues.apache.org/jira/browse/IGNITE-5150
Project: Ignite
Issue Type: Bug
Affects Versions: 2.0

40M entries consume about 4Gb offheap memory. It might be proved by [[top]] command (RES value - JVM memory = 8Gb - 4Gb) or by summing all "Allocated next memory segment" printed in server log.
After all data preloaded metrics show the following:
{noformat}
[18:37:18,152][INFO ][grid-timeout-worker-#23%null%][IgniteKernal]
Metrics for local node (to disable set 'metricsLogFrequency' to 0)
^-- Node [id=dc009e3c, name=null, uptime=00:02:10:102]
^-- H/N/C [hosts=2, nodes=2, CPUs=32]
^-- CPU [cur=19.53%, avg=11.99%, GC=0.03%]
^-- PageMemory [pages=22527667]
^-- Heap [used=238MB, free=94.17%, comm=4096MB]
^-- Non heap [used=40MB, free=68.18%, comm=45MB]
^-- Public thread pool [active=0, idle=0, qSize=0]
^-- System thread pool [active=0, idle=10, qSize=0]
^-- Outbound messages queue [size=0]
{noformat}
pages=22527667 seems to be wrong, otherwise offheap memory size would be 22527667 * 2KB = about 43Gb.
