[jira] [Commented] (CASSANDRA-12221) Maximum Memory Usage Reached -
NoSpamLogger
[ https://issues.apache.org/jira/browse/CASSANDRA-12221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15381723#comment-15381723 ]
Wei Deng commented on CASSANDRA-12221:
--------------------------------------
See CASSANDRA-5661. It's a cap to limit the amount of off-heap memory used by RandomAccessReader, and if there is a need, you can change the limit by file_cache_size_in_mb in cassandra.yaml.
> Maximum Memory Usage Reached - NoSpamLogger

> Key: CASSANDRA-12221
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12221
> Project: Cassandra
> Issue Type: Bug

> Environment: CentOS 6.8 x86_64, Cassandra-3.0.7
> Reporter: vin01
> Priority: Minor
>
> I see some logs which look like :-
> INFO [SharedPool-Worker-22] 2016-07-17 22:03:02,725 NoSpamLogger.java:91 - Maximum memory usage reached (536870912 bytes), cannot allocate chunk of 1048576 bytes
> INFO [SharedPool-Worker-33] 2016-07-17 22:18:02,747 NoSpamLogger.java:91 - Maximum memory usage reached (536870912 bytes), cannot allocate chunk of 1048576 bytes
> INFO [SharedPool-Worker-35] 2016-07-17 22:33:02,829 NoSpamLogger.java:91 - Maximum memory usage reached (536870912 bytes), cannot allocate chunk of 1048576 bytes
> INFO [SharedPool-Worker-31] 2016-07-17 22:48:02,834 NoSpamLogger.java:91 - Maximum memory usage reached (536870912 bytes), cannot allocate chunk of 1048576 bytes
> When i get these logs, CPU usage is quite high on the system.
> Are they expected? Log message also seems confusing and i am not sure what memory we are talking about here..
