I will try the suggested build later. I can't get it to segfault / overflow in gdb

Thanks. We've had some promising early results. I've not been able to
reproduce the problem so I'm relying on people who've experienced it.

Make sure your server's thread pool can accommodate the number of users you
schedule in siege.

Regards,
J.

Guillaume.

What's on sock.c:213 on your version?

I'm looking at an empty line on mine.

Same problem on Ubuntu Server 14.04.4 LTS (SIEGE 3.0.5) with >1000 concurrent users.

That's a really old version. Could you try this one from the source
distribution:

Yes, that's the problem with Ubuntu LTS.

It works with the current version!

I have the same problem. Debian Jessie running siege 3.0.8-1. Here is the debugger output:https://misterunknown.de/static/siege_gdb_screenlog.txt

Marco,

I can't pin point the problem based on this but it looks like it might be
in name resolution. Could you try adding the server name to /etc/hosts and
run it again?

Hi Joe,

you were right. It seems to be a problem with names having an AAAA record (IPv6). When I assign the name to an IPv4 address in /etc/hosts it works like charm. When I assign an IPv6 address in /etc/hosts it fails.

The name I initially used was "misterunknown.de" which has both, IPv4 and IPv6 resolution.

Thanks for the feedback. I'll try to see if I can find a solution but my
hunch is that resolver doesn't scale. (I've seen this in the past with
other resolvers)

Maybe it is possible to cache the name resolution anyhow?

I tried doing that in the past, I might try again. The architecture is more
suitable now.
