[et-mgmt-tools] RE: et-mgmt-tools Digest, Vol 18, Issue 7

[Marc Mondragon]

FWIW, I have seen this as well ... usually after a weekend.  In my mind
I have been blaming logrotate.  My fix is the same as Jan's, stop dhcpd,
stop cobblerd, start cobblerd and finally start dhcpd and all is well.

I have been running this on a RHEL 5 server if it matters.
