[rrd-users] Redefined Subroutines Error

[j.halifax2 at seznam.cz]

Dear All,

Could anybody advise please in solving the following problem?

I upgraded FC14 to FC16 and since that time mrtg w/ rrd stopped working, giving
me the following
error messages in its logfile:

-- Started mrtg with config '/home/drleos/mrtg/cfg/kwgov-http.cfg'
-- Subroutine SNMP_Session::pack_sockaddr_in6 redefined at
/usr/share/perl5/Exporter.pm line 67.
-- Subroutine SNMPv1_Session::pack_sockaddr_in6 redefined at /usr/share/perl5/Exporter.pm line 67.

Next call (after 5 min.) says:
-- Started mrtg with config '/home/drleos/mrtg/cfg/kwgov-http.cfg'
-- 2011-11-27 21:41:06: ERROR: I guess another mrtg is running. A lockfile (...xxx.cfg_l) aged 296 seconds is hanging around. If you are sure that no other mrtg is running you can remove the lockfile

I tried Perl, Fedora, mrtg, but no solution anywhere...

Any idea how to fix it, please?
Thank you so much.
