I have a small computer that I am running a video application on (video conferencing-style). At inconsistent times, it will 'lock up' - video will freeze, if I am telneting into it from another computer, the connection will crash, no keyboard or mouse input will be registered (even caps lock will not cycle).
The computer uses:
- Intel Atom D525 1.8 GHz (Dual-core)
- 2GB RAM (DDR2)
- Jetway Mini Itx Mobo
- NaND mini IDE flash module (4GB)
My first concern was that it was overheating, but that doesn't seem to be the case. The highest temperature I've recorded on it was 130 F (yesterday the CPU, RAM, and IDE were all between 120-130). Now everything is running a little cooler (110-117 F), although the air temperature is lower today (system is currently running with the backs open). The flash module is rated to about 160 F, and that is the lowest rating of the system. Interestingly enough, we haven't had any crashes today.
I also checked the load on the CPU and RAM. The application never uses more than about 200MB of RAM, and 53% of the total CPU (output is listed as around 105% CPU, but that is of one core -> 53% total CPU).
I am pretty sure it's not a defective part, because all of our machines do it sporadically. All of them are running Debian Squeeze.
EDIT: It locked up this morning, and I checked all the temperatures, and everything was between 95-110 F, so I'm pretty confident the problem is NOT heat.
