[Bug 534623] Re: sshd segfault at 38
I have other version of Ubuntu server running on the same host without issue as well as some other Linux distributions. The only thing different with this is it's now my only my 2nd 9.10 64 or 32 bit Ubuntu server running. The processes on other Unix boxes (ssh into the box to launch rrdtool) was running fine on a 32bit 2.4.18 linux kernel with sshd OpenSSH_3.7.1p1, also a VM on the same host VMWare server. I first moved all incoming ssh connections to to a new Ubuntu 9.10 64bit server and had issues with sshd dying and sometimes the whole box dying. I built a new 9.10 box, also 64bit and move the incoming ssh processes to this new box/vm. It had the same problems as the first 9.10 server/box/vm. The first 9.10 server has had no issues since I'm not hitting it with a huge amount of ssh connections any more (they were moved to the 2nd 9.10 box). So I'm guessing there could be something else at fault, but it seems all the ssh connections are triggering the other issue if ssh itself is not at fault. Is there any other troubleshooting I can do on my current 9.10 box that would get to the bottom of this? I hate to have to build a 9.04 box to see if it does the something as it takes me a while to update all my Unix boxes that ssh into the Ubuntu server, and I've already done it twice.

May be a hardware related problem.

I've had the server crash also, just now, I'm just not sure if it's sshd that's causing the problem or if sshd is just reacting to some other issue with ubuntu server 9.10.
