Hi,
I'm using linux 2.6.21.5 and our kernel is freeze.
The problem I'm facing is, when I create a software bridge using
*$brctl* command. and add two interfaces say, eth0.0 and eth0.1, this
way...
$brctl addbr br-lan
$brctl addif br-lan eth0.0
$brctl addif br-lan eth0.1
When I send traffic from a host connected to one port to host
connected at other at or above end 60Mbits/sec ,
soon all the *memory is dried up/consumed and and system crashes.*
Observation:
On initial start up:
$cat /proc/slabinfo | grep skbuff_head_cache
skbuff_head_cache 120 120 192 20 1 : tunables 120
60 0 : slabdata 6
Before crash:
$cat /proc/slabinfo | grep skbuff_head_cache
skbuff_head_cache 4260 4260 192 20 1 : tunables 120
60 0 : slabdata 213 213 0
Can any one help me to refer to some patch or point to some location
in code from where memory is failed to deallocate.
Thanks,
Sharad.
Hello Sharad,
What type of packets & packet sizes are you sending ? Also which
ethernet driver are you using?
In a problem what I faced before, we had a similar situation, but we
used bonding driver which wasnt allocating enough memory for some
fragments causing a leak and subsequently a panic at a later stage.
You might want to try dumping & match the allocated size for each skb &
match with the corresponding free.
Regards
Ramesh
