Description Joel Matuseski 2007-05-18 17:58:26 UTC

Description of problem:


Version-Release number of selected component (if applicable):
net-snmp-5.1.2-11.EL4.10

How reproducible:
100%

Steps to Reproduce:
1. Wait until UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 4294967295
2.
3.
  
Actual results:
Counter gets stuck at 4294967295

Expected results:
Counter should wrap over to zero

Additional info:
This is handled by net-snmp's offical patch located at
http://net-snmp.cvs.sourceforge.net/net-snmp/net-snmp/agent/mibgroup/ucd-snmp/vmstat.c?r1=5.7&r2=5.8

I checked the source RPM tarball and patches for the version listed and vmstat.c
shows the pre-patched version at net-snmp's sourceforge link above. 

The counter sticking throws off our monitoring and instrumentation for the
servers. A reboot is the only current fix.
