vin01 commented on CASSANDRA-12221: ----------------------------------- Thanks. So shouldn't it be a WARN/ERROR? does it cause any issues ? can it be responsible for High CPU Usage? > Maximum Memory Usage Reached - NoSpamLogger > ------------------------------------------- > > Key: CASSANDRA-12221 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12221 > Project: Cassandra > Issue Type: Bug > Components: Core > 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.. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
