Willstrand I didn't have problems with rhel ws3 or with the kernel it came with. I removed it in favour of debian a long time back, when debian/etch r0 was released. I have been running debian etch r2 (4.0 r2) ever since, which comes with kernel (2.6.18-5-686). As you might notice from the mentioned kernel versions, I tried upgrading to kernels from lenny/debian and sid/debian hoping to find a solution. I tried from 2.3.13 - 2.6.25 from both debian packages and vanilla sources (as they are called), but the problem persists. It started and is continuing on debian. I have 2 ISPs hooked into this box. One is CIR, the other is ADSL. The ADSL runs over pppoe. I don't know if the 2.4.x kernels support pppoe. The 2.6.x kernels do. I need to run 2 ISPs on this box seemlessly. The last rhel version I used was using kernel 2.6.9. I'm going to grab that and see if that helps. I need pppoe, iptables, vpn, scsi with raid support, smp, and a around 8000 file descriptors to run stable on this box. M. Istehbab
