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.. was: 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 see these logs, CPU usage is quite high on the system.
