Log message:
Let the config parser make use of the mib_string2oid().
If a descriptor is not found in the loaded MIB files it falls back to
the old smi_oid2string(), which then throws a deprecation warning. This
won't trigger for most cases in the default install, but the
UCD-DISKIO-MIB and dependencies aren't included (yet?) (which can be
fixed by manually including them via "mib directory") and there's a

sequentially closes all sessions. If the session with the outstanding
request is closed before the second session the request is retried
before said session is cleaned up and it will try to send it over a
conn_ax which at that point has been set to NULL, resulting in a
SIGSEGV.
