Hello all,
I have a big problem with my freebsd 7.2 with one process (MPD 5.3)
my server is a dell R300 with 2 Gigas
All seems to be clean but ramdonly the process mpd5 crashed.
It can crash one or two or 5 times per days.
I have detected something :
when i lanch TOP -S command
i can see the process increase to approx 92180K and 87904K (for RES)
after it crash without any error into log files
I have never seen the process mpd5 consum more than 94000K it always crashed before.
the command limits show me that :
is there anything wrong ?
when i launch
dmesg
i have a lot of messages like that:
When i launch netstat -w 1 -I bge0
There is no packets in error.
Last thing, the result of command sysctl -a
I don't understand what's happened because only the process mpd5 crashed
all the rest of the processes continues to run normaly.
I have put a script that reload the mpd process but it isn't clean
and i want understand what happened.
if someone can have a look at this it will be very usefull.

I have put a script that reload the mpd process but it isn't clean
and i want understand what happened.
