Subject: snmp plugin: Don't try to free the request PDU - it segfaults for some reason.
X-Git-Tag: collectd-4.1.4~1
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=b641906ca7c4652e5234dce65ca43dd875f3a7ae;p=collectd.git

snmp plugin: Don't try to free the request PDU - it segfaults for some reason.

According to other code I've seen this is never done by anyone else, so this
must mean that the snmp library takes care of this somehow. Man, I love well
documented libraries!
