We are running Java 8_45 on Linux. We are seeing period of time when ParNew pause time steadily increases from 5ms to over 1 second. As the pause time increases, User CPU time increases in proportion. Then, just as suddenly as the problem started, it ends and pause time returns to 5ms.
GC log attached. The issue begins around 2016-02-28T17:05 and ends at 2016-02-28T19:33. During that span of nearly 2.5 hours, ParNew pause time steadily increased from 5ms to 1.47 seconds. CPU utilization ranged from 95-99% idle during this period. Percent free memory did not change during this period. Any ideas what might be causing this? ________________________________ This message may contain confidential information and is intended for specific recipients unless explicitly noted otherwise.
