CPU overloaded
-
I'm running release 1.0 on a 1.1GHz Celeron with 128MB RAM (it's an old Dell PowerEdge server from a few years back - it even ran Exchange Server at one point!). I keep finding, though, that the CPU is at 100%. Running 'top' shows me that the top two processes are:
miniupnpd 67%
syslogd 28%So between them, those two processes are munching 95% CPU. I'm not sure that either is doing a great deal (syslogd doesn't seem to be picking up logs from any of my installed packages). There are usually about 8-12 users behind the PFSense box on my LAN, plus up to about half a dozen VPNing in. Is this kind of CPU usage normal, or is there something amiss here? Is a 1.1GHz Celeron a bit on the low end? (Screen dump from 'top' is pasted below). Could it be the CPU usage that's causing my occasional dropped IMAP connections?
Also (unrelated): the blog post announcing version 1.0 doesn't seem to have/link to a list of changes since the last RC/beta. Does anyone know where I can find that (apart from the CVS)?

Your hitting the miniupnpd race bug. Restart the service from Status -> Services when this happens. Check over on the miniupnpd thread for more info.

Thanks for answering. I couldn't find the miniupnpd thread (neither forum nor google search had much to contribute). Could you please point me in the right direction? For the record, my syslog is chucking out messages like this:

Please reinstall the package. Those errors have been fixed. The latest version is 20061023.
