Is anyone else having trouble with zenperfsnmp from version 2.0.4 hanging?
Oddly, only one of my half-dozen 2.0.4 systems is experiencing this, but
after running for varying periods of time on the order of 1 to 8 hours,
it just hangs hard. It appears to hang waiting for some network traffic.
Server specs:
x86_64-redhat-rhel4as, GenuineIntel Intel(R) Xeon(TM) CPU 3.00GHz, 16xCPU,
3002MHz, 9991MB
