VMware guest hangup and "NOHZ: local_softirq_pending 100" logged
Issue
- VMware guest server didn't repsond.
- When the server didn't respond, memory and swap were consumed very much. Most of them were used by httpd and dovecot.
- Service processes continued to output log files at that time, so it doesn't seem hangup was happened although the server was under very high load.
Environment
- VMWare ESXi5.1(Host)
- Red Hat Enterprise Linux 6.3
- kernel-2.6.32-279.19.1.el6.x86_64
