Haproxy failing to start after VM move (Debian 8 [systemd]) (9 replies)

Hi,

I hope someone can offer some insight here, as I'm currently at a bit of a
loss, and our service is down. We are running HAproxy 1.6.1 on Debian 8
virtuial machines. I was moving our 2 instances to a different size VM,
however, when I rebooted they did not come back up.

I can't even run the haproxy binary file. Here's what I get when I try:

./haproxy
Illegal Instruction

sudo ./haproxy
[no output]

./haproxy -v
Illegal Instruction

sudo/haproxy -v
[no output]

Same thing if I try to check the config with -c -f (though I don't think
this is a config issue).

Here's what I have in kern.log:

Mar 7 11:41:41 rproxyws1 kernel: traps: haproxy[4031] trap invalid
opcode ip:4843a0 sp:7fff51856ac8 error:0 in haproxy[400000+cf000]

One thing that does seem to have happened is a kernel update during the
move (from 4.1.5 to 4.4.0), but I've manually renerted to the old kernel,
but the new problems remain.

Does anyone have any ideas!?

Thank you!

Scott
