Segfault in nginx 1.0.5

Hi guys,

I'm seeing a small segfault in 1.0.5

It is strage there is something triggering it as it happens at the same time every night. It isn't triggered by crontab as I have nothing that runs at that time.
I'm running the keepalive patch (however this was happening before I installed it).

Anyway here is the backtrace
