All 5.4-STABLE systems were updated from 5.3-STABLE. Connecting to a server with ssh and pressing ctrl-c instead of entering a password results in a process that won't terminate. After ten processes have been created like this, login via ssh is (of course) not possible any longer... I do see this behaviour on several servers with FreeBSD 5.3-STABLE from 16.11.2004 (SMP) and one server with FreeBSD 5.4-STABLE from 11.05.2005 (SMP) (HP ProLiant DL360/380) and I don't see this on another server with FreeBSD 5.4-STABLE from 06.11.2005 (SMP) and FreeBSD 5.4-STABLE from 16.11.2005 (single processor AMD Duron) (Dell PowerEdge 2800 and Home-PC with ASRock-Board) so this is really strange. Below is output of ps and sockstat with the relevant entries as found on one of those misbehaving systems. Ideas welcome!
