Internal Error: SubSystem VPR20KMAIN

Hi All: I've just recently ran into a problem about 65% though the fitter stage of my design: Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera...

Hi Adrian:

Thanks for the reply. I did have a third message as well, related to the TimeQuest engine during fitter. There are two of us who have had this issue, and it seems it might be related to the Cisco VPN client we're using.

I disabled the VPN during the fitter stage and it seem to complete OK.

I'll run the ram checker over the weekend and report the results. I'll also let you know if I can find anything more definite with the issue.

It's not completely random like I would expect from memory fault, but it's random enough to make me scratch my head.

(I received the line 722 error at least 3 times now with reboots in-between)
