Hi there, since a few hours I'm getting messages like the following in my syslog. The strange thing is that they only seem to pertain to processes doing SNMP (mrtg and snmpget.) I don't think it's an "out of memory" issue since there is PLENTY of swap available (512M,) and apart from 10 FTP processes there's not much load on the machine.

go away -- but that's not a real solution since I'd like to know WHAT caused this. Apart from that we're not running Windoze where frequent reboots are normal, are we?! ;-) Any ideas?!
