It's not a thrashing issue as I don't have any swap. The 8GB of ram has been sufficient memory for all tasks thus far. I have no objection to allocating some swap space if it could resolve the issue. Actually, Grant and you both suggested possible heat issues which has just made me think that I should check for dust build up in the CPU heat sink. There so much dust where I live that I have to vacuum dust build up from the case. The sensors tool reports 51C, it doesn't appear to be running too hot, but I don't have a baseline to compare it to. I see I need to implement monitoring for this machine once it's stable again. k10temp-pci-00c3 Adapter: PCI adapter temp1: +51.0°C (high = +70.0°C) (crit = +71.0°C, hyst = +66.0°C) I'll give the inside a clean this weekend and see if there's any improvement. Thanks for the suggestions. Regards, Carlos
