There's no obvious disruption of operation, existing ssh connections seem undisturbed. The messages occur in a group of about fifteen, one second apart. The machine has been up about three days, with only one occurrence so far. Can't tell if this is new or old behavior, I've never manually checked /var/log/messages for sshd errors until now and didn't save the security run email from the 13th.. Might it be of significance? Thanks for reading, bob prohaska
