Its primary function is a Squid caching proxy. It has 2 10k RPM SCSI-3 disks, 74GB each. It has 2 processors, each a P3-1400, and the kernel is SMP enabled. The problem is that every time I start using the second disk for anything significant, like logging or caching files for squid, the system locks up after some hours or days. There are no unusual messages in the syslog, it just locks up completely and unexpectedly. It has been running fine for quite a while now with the second disk mounted, but doing nothing. Can anyone help me find the root of the problem? I don't even know how to begin to troubleshoot this. My next step was going to be to upgrade to 4.10, but I would prefer not to at this point.
