We still use RedHat 7.[23] The system works using rp-l2tp and/or pptpd with pppd. On the outgoing interface (the one that sends traffic to the Satellite we were using CBQ and now we use HTB queuing discipline. The kernels range from 2.4.6 to 2.4.25 with some modifications (tcp_input). We tried with the standard kernel with the only change that the dev_alloc_name has been changed to support up to 900 names. Every few weeks (sometimes 2 days, often 3 weeks and sometime up to 9 weeks) the kernel freezes: nothing on screen or serial console except from some VJ decompression errors which we have at all times, even the Num-Lock does not respond. We tried to enable sysreq keys but those won't work either. 2 days ago we were able to catch the following message (12 hours before a freeze) : HTB: dequeue bug (8,12140714,12140714), report it please ! The Hardware are Dell PowerEdge with Perc2 or Perc3. We tried with HP servers and have the same problem. We tried different firmware releases for the Perc cards and still no change. The NIC cards are mostly Intel EEpro 100. We tried with both drivers Intel and community with no better results. The problem may be happening more often (every 2/3 days) when we simulate a lot of ppp connections/disconnections (80 users/minute), but in some cases it hangs even without having many users. The platform we run have between 25 to 200 simultaneous connections. Some have single or dual or even quad CPU's. And RAM between 512Mbytes and 4 Gbytes. We could not detect any parameters that would rise before the freeze (load, memory, swap ...) Could anyone give me some hint as to what to do/test more ? Where could the problem be ?
