When you get segfault ? Just when run nginx or some conditions are needed ? Could you use gdb ?

We're getting it during what we believe is normal operation, but not all the time. I haven't been able to find any certain conditions that give us the segfault. The nice thing though is that nginx recovers in a good way, but it's hard to transfer bigger files from the backend webservers running behind nginx.

Some times when can run for a couple of minutes without segfaults, but then get segfaults perhaps once a minute or more often.

I've managed to wrangle up a gdb, and the error is happening as per my earlier diagnosis.

The problem seems to be that ngx_cycle->files seems to contain null-pointers, and that the check for c->fd == -1 is not preceeded with a check for c == 0.

Please tell me if you need more info.
