Hello,

I'm running a stock redhat kernel (2.4.9-21) and when I left the server on this weekend running only apache, postgres and mrtg I got the messages below. It resulted in a total loss of service.

Is this bug fixed ? Or can anyone fix it ? I'm not subscribed to the lkm anymore so any replies please cc to [email protected]. Furthermore there where a load of emails from my cron daemon. Every time in pairs of 2.

Thank you,
Dennis Fleurbaaij
