rt_cache leak in 2.6.18
...etwork is
un-responsive. All IP forwarding stops and the server cannot be reached
from any network interfaces.
After diagnosing the issue, it appears that there is a rt_cache leak in
the kernel. At 5 minute intervals I collect the following two values:
`/sbin/ip -o route ls cache | wc -l`
`grep ip_dst_cache /proc/slabinfo | awk -F' ' '{ print $2; }'`
The first value represents the number of cached routes in the network
stack. The second value represents the number of cached route objects the
kernel has allocated.
After collecting the data for 8 hours, I have seen the cached routes c...

dst cache overflow in 2.6.8
...From what I gather this error means that the routing cache filled up. The
maximum size of the routing cache can be set by changing
/proc/sys/net/ipv4/route/max_size. The default on my mandrake install is
32768.
The current size of the routing cache can apparently be determined by "grep
ip_dst_cache /proc/slabinfo". On my router this value is slowly, but
constantly, trending upwards at all times. However, if I list the cache
with "route -Cn", or "cat /proc/net/rt_cache", I see significantly fewer
entries than what slabinfo reports.
Two things have changed since t...

"dst cache overflow" messages and crash
Hi,
I regularly have errors (kernel: dst cache overflow) and crash of a
firewall under Linux 2.6.17 and the route patch from Julian Anastasov.
With rtstat I see that the route cache size increases regularly without
never decreasing.
I have this parameters:

Firewall sizing guidelines?
I have just completed the installation of a new firewall running
Shorewall 1.4 on Mandrake 9.2 for our campus network. It appears to
be running fairly well so far, but is generating significantly more log
entries than our previous linux 2.0.x firewall...
Our previous firewall enjoyed more than 6 years of 24/7 operation with
no downtime before we finally decided it needed more horsepower, and

Lustre Client - Memory Issue
Hi Guys,
My users are reporting some issues with memory on our lustre 1.8.1 clients.
It looks like when they submit a single job at a time the run time was about
4.5 minutes. However, when they ran multiple jobs (10 or less) on a client
with 192GB of memory on a single node the run time for each job was
exceeding 3-4X the run time for the single process. They also noticed that
the swap space
