We've recently had a report of a bug with the generation of
request IDs. When this ID reaches the maximum value,
it wraps back to 0, which is interpreted as a failure to send
the packet. This triggers a double free of the PDU, which
can cause the agent to crash.
See the thread
"glibc double free error on snmp_sess_close"
on the coders list for details.It doesn't happen very often, but is fairly simple to address. Attached is a patch to fix this - not just for the Reqid (which is where the original problem hit), but also for the other IDs. Question: is it worth applying this immediately so that it can be included in the 5.5 release, or should we wait? Dave
