Thanks for the input. Basically we had aolservers running and while serving pages, it's also doing some heavy load processing from a ton of scheduled custom written procedures. Aolserver crashes and segmentation faults are fairly frequent and the logs at the time pointed to these running threads as a probable cause. Possibly a configuration issue, but I remember we tried fiddling with those numbers and it never really helped. So basically, what I'm currently beating my head over is to build a much cleaner and better way of handling all the load but in so doing, I'm not entirely sure whether or not to spawn a lot of threads for the jobs, or basically keep it to a minimum.
Judging from Andrew's post, it would likely be better to reuse threads but I'm not entirely sure how that happens. I mean, everytime you'd invoke ns_thread begin/begindetached, you are creating a new thread already, no? How do you reuse them? This is probably a stupid question, but is there a distinction between the threads and connection threads in aolserver? I know the connection threads are probably the connections to the database (I think). Thank you all for your insights and hope to hear more!
