    Three days in a row, my old Mac Mini have hanged due to no obvious reason. :(

    I got the following errors in the log after reboot:

    panic(cpu 0 caller 0x001A49CB): Unresolved kernel trap (CPU 0, Type 14=page fault), registers:

    Judging by the age of the Mini and its server OS (6+ years) the most likely culprit of the problem is that the hard drive is failing but the system hanging could be the result of a range of hardware or software issues (HDD, RAM, Power Supply failing, cooling fan failing, CPU overheating, corrupted OS and/or corrupted data, etc.). You could try running HDD analysis and memory testing programs. If the problem does end up being the HDD or RAM then you could try replacing those parts and transferring or restoring from the old drive if it is still working enough to do the data transfer. If or when you open the Mini check for excess dust that could be obstructing the air flow and fan rotation. Make sure the Mini has enough air flow to properly cool the machine.

    Try Apple Mini forum. There are some very knowledgeable people over there.

    The log you provided is too short. The last loaded and unloaded framework may provide a good hint.

    Run memtest on the RAM? Memory or the HDD can both develop failures due to age. And I believe you are way passed the time the hard drive should be replaced. Those old ones didn't last very long... I get nervous when they're more than 3 years old.

    Thanks for the answers guys!

    The OS resides on an external drive.

    As it happens, I have another Mini bought the same day. I have switched the machines, and now it works.

    Hence, some sort of Hardware related problem.

    Now I have time to investigate the broken Mini further. As you say, it's probably RAM or CPU (Heat?) related.

    And yes, this machine *is* old. I have some domains on it and I also have a new Mini Server, but haven't got the time or effort to move the domains, SQL, mail and other stuff...

    Regarding the lenght of the error report; That was all included in the "Your Mac was not shut down properly"-message.
