Not a silly question at all! The only problem is ... I have no idea what oom-killer is. But a google search show me I have some new reading to do : ). I can say that I have 32GB of RAM and this is not a virtualized box. I will be looking into this, but I welcome any input anyone may have that may shed more light on this.

Silly question - did you check to see if oom-killer needed to free RAM during the log rotate process, and decided that PF's DNS daemon was going to be the victim? If you have PF running on a VM, I guess that you could throw some more RAM at it and see if it fails again. Then again, it is the end of the semester, and this may only be a placebo fix if the real cause is network load or a rogue client that will soon be gone for a month or so... -Arthur ------------------------------------------------------------------------- Arthur Emerson III Email: [email protected] Network Administrator InterNIC: AE81 Mount Saint Mary College MaBell: (845) 561-0800 Ext. 3109 330 Powell Ave. Fax: (845) 562-6762 Newburgh, NY 12550 SneakerNet: Aquinas Hall Room 11 ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
