[plug] Memory question - Debian Sarge

[bulkniffum]

I had some issues with what i believe is the same problem.  I run my linux 
box as my gateway to the adsl modem (in bridged mode) with traffic 
shaping.. every 2-3 days it would stop responding... if i got it in time, i 
could see some interesting messages in the log files....

Jun 28 10:53:03 hoochie kernel: printk: 5 messages suppressed.
Jun 28 10:53:03 hoochie kernel: dst cache overflow
Jun 28 10:53:04 hoochie named[26793]: sysquery: sendto([192.12.94.30].53): 
No buffer space available
Jun 28 10:53:09 hoochie kernel: printk: 95 messages suppressed.
Jun 28 10:53:09 hoochie kernel: dst cache overflow

I believe it was running out of network buffer.. I think it was caused 
ultimately by using 'emule' on one of the windows machines on the network, 
also some of my friewall rules reguarding the blocking of some ICMP 
packets... which i think caused it not to close connections that should 
have been closed (well, it had to time out).  In the end i ended up putting 
in more ram (I think it has 300MB ram now) and recompiled the kernel.  Now 
it doesn't seem to have any problems.

Also, i had other problems with another box that one day started to 
freeze.. after a few hours... after weeks of work on it it worked out to be 
some power management 'features' in bios that i had turned on one random 
day.. which when i turned them off the box stopped freezing.. and hasn't 
freezed since.

I have no idea if this is of any help, hope it is.
