SLS DHCP server resetting itself

About a month ago, I set up a new mac mini running OS X server 10.6 at a small business to provide filesharing, calendars, etc. Last week, I also switched the DHCP server from the router to the Mini server because the router could not provide static mappings that were needed for the printers.

However, within the 5 days it has been in use, the DHCP service on the Mini has turned itself off twice. The subnet information is also reset and disabled.

Searching through the logs, I came across these two messages:
servermgr_dhcp:bootp config:Notice:Created default configuration file
servermgr_dhcp:bootp config:Notice:Created 1 default subnet records

Can anybody tell me what's going on here and how to keep it from happening again?

 

Logging for DHCP was set to "High (all events)", but these are the only two lines indicating a problem. Those errors were found in the system.log. Is there another place to look for more information?

 

thanks for the tip. That's fairly new territory for me, but hopefully it will provide some more information to work off of if/when it happens again.

 

In case anyone else is having this problem, it seems this problem arises when Server Admin locks some files while it is open. I've been making a point to close server admin anytime I'm not making a change, and haven't seen this problem for several weeks. (Still, it's a little unsettling knowing it's that easy to mess up the DHCP).
