This message seems to be enhanced always by the same task because it appears always at the same hour but not every day. This server has several IPv4 and IPv6 addresses. Could this behavior be linked to this thread : http://lists.freebsd.org/pipermail/freebsd-net/2007-August/015153.html I checked the source code and the rtfree function in stead of RTFREE_LOCKED version is called. >How-To-Repeat: Random behavior => Not easily reproductible >Fix: Maybe replacing rtfree by RTFREE_LOCKED as told in the ML thread. >Release-Note: >Audit-Trail: >Unformatted:
