The RAM was upgraded by our local Apple store in the hopes of avoiding bad RAM issues. The new chip could be bad but crashes occurred both before and after the RAM upgrade. The lookupd process sounds promising. Sounds like lookupd problems interfere with crash logs being written which fits our pattern. I can think of two things that might contribute to this...there is an attached FireWire drive and we have an NFS server on our network. The Mini is not set up as an NFS client but I think it could be receiving signals from the NFS Server. I am probably reaching here but maybe it will lead to the answer. The server went down again this morning so I took the opportunity to upgrade to FM Server 8.0v3. If/when I get this figured out, I will certainly post the info here. Thanks.

No except that I recently upgraded the RAM on the machine from 512 MB to 1 GB and a 64 MB cache was more appropriate when the machine had only 512 MBs of RAM. Even with the RAM cache so low, I am still getting a cache hit % of 99-100. I will increase it and see if it helps. Thanks.

Thanks for the suggestion Xochi. I thought I had done this already but I just noticed there are separate energy saver settings for the UPS...one of which is put hd to sleep whenever possible. I just unchecked this and turned off all other energy saver settings other than put the display to sleep.

Hi all, I have been having a problem with our FM Server. The computer freezes at irregular intervals, requiring a forced reboot. I have searched various forums and have yet to find an answer. In the course of looking through these forums, I read that someone likes mysteries...so here's one that has me stumped. First, some details Mac Mini 1.42 GHz Power PC G4 1 GB RAM External FireWire drive for backups UPS dedicated FileMaker server Mac OS 10.4.6 FM Server 8.0v2 hosting 50 files total size 600 MB for 20 local clients (all 8.0v2) 64 MB RAM for db cache The problem we are having is that the machine freezes almost weekly but not at any predictable time or date. Sometimes, this happens in the middle of the night when no clients are connected to the server. The first sign of this is usually when FM becomes unresponsive to clients with the spinning beachball. When this happens, the mouse still responds on the server. I can sometimes move windows in the Finder and between various screens in FM Server Admin. Trying to open an app or select a menu item in FM Server Admin or do just about anything else, causes the machine to become unresponsive (although the mouse still moves the cursor). I am still able to ping the mini. I have tried reinstalling and upgrading the system software and FM server from scratch. Crash logs have not provided any useful clues and are not being written from FM Server when this happens. I had the macine into the Apple store recently and their hardware tests could not find anything wrong with it. I have read some posts that say do not use a Mac Mini as a server and others that say it works fine. The drive speed seems to be an issue but does not explain why it would crash in the middle of the night when nothing is happening. I am wondering if anyone has any ideas that would explain this or help me to figure out what is going on. I would appreciate any help you can offer. Thanks.
