The snmpd service is crashing after some time on a Virtuozzo node:

 ~# /etc/init.d/snmpd status
 snmpd dead but pid file exists


The issue is caused by the bug PSBM-39087.


The bug is fixed in Virtuozzo 6 Update 11. Install pending updates to resolve the issue.

If updates installation is postponed, use snmpd without rmond as a workaround.


  1. Find the rmond mentions in snmpd configuration:

    ~# grep rmond /etc/snmp/*
    /etc/snmp/snmpd.local.conf:dlmod        RmondMIB        /usr/lib64/rmond/
  2. Comment out the line with /usr/lib64/rmond/

  3. Restart snmpd:

     ~# /etc/init.d/snmpd restart


  1. Enable core dump generation for snmpd by executing

    ~# DAEMON_COREFILE_LIMIT=unlimited /etc/init.d/snmpd start
  2. Change the path where the core dump is to be saved:

    ~# echo '/tmp/core_%e.%p' | tee /proc/sys/kernel/core_pattern
  3. The obtained dump may be analyzed with the help of gdb:

    ~# gdb /usr/sbin/snmpd core_snmpd.XXXX
    Core was generated by `/usr/sbin/snmpd'.
    Program terminated with signal 11, Segmentation fault.
    #0  0x00007f71c40de15f in snmp_oid_compare () from /usr/lib64/

    The presence of snmp_oid_compare function in the dump indicates that the issue is related to the bug PSBM-39087.
