policy-weight -spawn $csock error after power out reboot

[David Southwell]

Hi

FreeBSD dns1.vizion2000.net 7.2-RELEASE-p3 FreeBSD 7.2-RELEASE-p3 #0: Thu Aug

david at dns1.vizion2000.net:/usr/obj/usr/src/sys/GENERIC  amd64 [on intel quad]

Following an abrupt power system failure and a system reboot this server now 
gets this error in maillog:

  postfix/policyd-weight[9622]: warning: cache_query: $csock couln't be 
created: connect: No such file or directory, calling spawn_cache() 

No other problems. Just in case it was due to a retained. pid I deleted the 
.pid file followed by a normal shutdown and reboot - but am still getting the 
same problem.

Thanks in advance for any guidance

David
