From d077d64e54c6162e410c4227fd75d090758594ea Mon Sep 17 00:00:00 2001 From: abrist Date: Tue, 28 Jul 2015 15:20:38 -0400 Subject: Fix for unclosed filehandle in pst3 on Solaris On Solaris, check_procs uses pst3 instead of /bin/ps (see http://monitoring-plugins.org/doc/faq/ps-on-solaris.html for background). There's a small bug in pst3 which causes it to NOT report some processes that are at the end of the process table, at least on very busy systems (we noticed this on a CoolThreads T5240 with load averages up to 90). The bug is that a filehandle is not properly closed. Thanks to jwinkle01 for finding and patching the bug.
