snmpd issue - could not create socket

Solution Verified - Updated -

Issue

  • I have two questios about the snmpd issues which occurred at our customer's site.

    • Problem 1:
      • Following snmpd messages were logged heavily. What is the cause of this issue?
    Oct 15 00:00:17 server51 snmpd[17250]: could not create socket 
    Oct 15 00:00:17 server51 snmpd[17250]: could not open /proc/net/if_inet6 
    
    • Problem 2:

      • The customer reloaded snmpd service at 00:00, Oct 16 to restore to normal situation. Just after that, however, snmpd crashed with segfault.
      • It looks that this issue is related to 'problem .1' from the messages. Perhaps it will recover without any problems if restarting snmpd service instead of reloading snmpd. Is there other way (except restarting snmpd) to recover if 'problem .1' occurs?
