NoSpamLogger
[ https://issues.apache.org/jira/browse/CASSANDRA-12221?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
vin01 updated CASSANDRA-12221:
------------------------------
Description:
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..
