2.6.14.3 and page allocation failures..

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi,
     I am seeing page allocation errors and I have a snapshot of the
/var/log/messages.

My Hardware configs are
Dell 750, using e1000 driver(e1000-6.2.15)

model name      : Intel(R) Pentium(R) 4 CPU 2.80GHz cache size      :
1024 KB

             total       used       free     shared    buffers
cached
Mem:       1035396     573568     461828          0      24812
40400
-/+ buffers/cache:     508356     527040
Swap:      2097136          0    2097136

Observed the failures after about 9-10 hrs of running network traffic.
I am assuming that it has something to do with the e1000 driver page
allocations here....I would appreciate if anyone can help me in
figuring out what is going wrong with this.
