Hi Ken, I have not see it again. I am wondering if it was an issue of not having swap. It happened last weekend when some level 0 dumps over nfs are run, so its possible too much demand on memory and 'bad things' started to happen. I have since enabled swap and no issues since. On another box which has a similar mix of spamd,clamav, sendmail, no issues at all. ---Mike >That said if there is a bug it's likely to be something fairly difficult >to reproduce (lots of people are running 7.2-PRERELEASE and so far only >two reports of this issue) so it's not a shock for you to have only had >it happen once so far.
