I'm not sure if we're talking about the same thing, but a few months
ago I
was experiencing occasional system crashes. After reviewing the logs and
googling I finally came up with a solution (at least, so far). I've forgotten
the details, but in general it had to do with the size of the packets
arriving over the network on my 100Base-T connection. Even though the system
as a whole had plenty of memory, it was unable to allocate sufficient buffer
space quickly enough. The solution was an entry in /etc/sysctl.conf to
increase a memory parameter:
$ cat sysctl.conf
#
# /etc/sysctl.conf - Configuration file for setting system variables
# See sysctl.conf (5) for information.
#
#kernel.domainname = example.com
#net/ipv4/icmp_echo_ignore_broadcasts=1
vm.min_free_kbytes=16224
HTH!
Cheers!
