Hi, A few days ago we were discussing a problem I was having with clamd reporting a corrupt database.

I've since learned there was a cooling problem with the processor and started receiving events like these on the host: kernel: [73788.355981] [Hardware Error]: Machine check events logged kernel: [73914.635576] CPU4: Package temperature above threshold, cpu clock throttled (total events = 5538406) kernel: [73914.635581] CPU0: Package temperature above threshold, cpu clock throttled (total events = 5538398) I've since corrected the cooling issue, but am still receiving messages such as these on the kvm guest: [169245.360511] clamscan[27448] general protection ip:7f125f2e6ffb sp:7fff117566f0 error:0 in libclamav.so.6.1.11[7f125f229000+9ce000] [29016.445470] clamd[1110] general protection ip:30df2c3981 sp:7fffa08f4fe0 error:0 in libclamav.so.6.1 .11[30df200000+9ce000] I realize this may be a problem with the system and not specifically clamd or clamscan, but since that is how it is currently presenting itself, I thought someone may have some ideas of what is happening here? Is there any way to determine if the processor is permanently damaged due to overheating? Could this be related to library or system corruption caused by the processor overheating? I've reinstalled all the clam applications, and there haven't been any further messages in the logs except for this one clamscan line. I'm hoping there are some smart people here that can tell me with certainty that it is indeed the processor and I should replace it as quickly as possible. Thanks for any ideas.
