I recently heard from a friend experiencing this issue, which led me
to this bug report.

Hi Graham,
  In snmpd version 5.7.3+dfsg-2 the init script was changed to follow the
standard LSB init setup.  This has retries built into it (or the
start-stop-daemon does anyway).  So I suspect this has been fixed, although
not in the way mentioned in the bug report.  Before I close this bug off,
are you asking to clean up old bugs or are you having the same issue?

Is this fix really still pending?

Bug#790303: snmpd: snmpd fails to restart during logrotate if it is too busy

[Paavo Hartikainen]

Package: snmpd
Version: 5.4.3~dfsg-2.8+deb7u1
Severity: normal
Tags: patch

If snmpd is too busy to finish for restart within 2 seconds defined 
in /etc/init.d/snmpd, it is accidentally left not running after 
logrotate.  My solution was to check whether it has finished and add 
conditional delay.

This is how I solved it for production server:
