I have not a lot of experience in running programs that take several hours to end.
I'm running an attack which complexity is dominated by the LLL function
It has been running for several hours now and I have no idea how well it's doing, or if the thing just crashed (I'm using sage in a virtualbox)
I've seen some people talking about syslog to continuously log
But I'm sure some people here have been in my situation and could share some light on this problem :)
