Last updated on AUGUST 01, 2016

Applies to:

Solaris Operating System - Version 10 1/13 U11 to 10 1/13 U11 [Release 10.0]
Information in this document applies to any platform.
This problem is triggered when there is memory pressure; causing the arc_reclaim_thread to run and trying to reap memory.

There is not much ARC to reap in the first place; causing this thread to continuously be activated and hogging the cpu. The hang is more likely to happen when the system has limited amount of cpus.


There is an alert about this. DOC 2033273.1.
