Re: Commands run from functions don't exit cleanly on terminal close (SIGHUP)?

I tried from CentOS but got the same thing.

However it might be confounded by the fact that I have to SSH to the centos box...

Just to clarify, you're seeing it exit *before* the loop finishes? This is what I see in the "sig" file:

Thu Oct 25 08:20:05 CDT 2012
START
Thu Oct 25 08:20:26 CDT 2012
HUP
Thu Oct 25 08:20:36 CDT 2012
DONE

The HUP is received but doesn't affect the process until the php command exits.

So you're just seeing this?

Thu Oct 25 08:20:05 CDT 2012
START
Thu Oct 25 08:20:26 CDT 2012
HUP
