Hi, To begin with, thanks a lot for the concern you all have shown to address my problem. This morning I have put in test9-bk25 image to see if the problem disappears. The result should be out in the next few hours. I hope it is OK if I send you the slabinfo in case the problem persists. I plan to test in stages. i) Just bridging, no iptables ii) With iptables. I have very limited set of iptables rules. In fact it is as simple as blocking icmp. There are no errors reported by ethernet devices. Anand PS : The latest test10 stops at the booting stage while initialising my aic7xxx scsi. So, I had to use bk25. > > Linus is right, this is probably a memory leak issue.
