How do you change the stack size? I've tried to find the -p flag for startup, but can't find any documentation on it anywhere...  Don't think upgrading is going to be possible for a little while, so have to work within the parameters of a 32 bit OS unfortunately. I've got storage down to 600 megs, and 210 threads. 1 box is running stable, but the other 4 are a bit flakey. How can I adjust the thread stack?

NOpe, this is a dedicated server.. We're running CentOs... How do you know we're running 32-bit version? I had to compile from source on CentOS, so just grabbed the binaries from the site and did a build from them. ?How are you guessing it's 32-bit?

Definitely not familiar with analyzing core-dumps or even getting them to run... I'm not a sys-admin, just the guy stuck trying to get our servers ready for an onslaught of traffic coming next week that I know we can not handle right now....

Then seriously, reinstall that server with a 64 bit OS. I haven't
heard of anyone thats been running 32bit Varnish in production for the
last two years and having it run stable. The CC-people did for some
time but I believe they migrated due some issues.

If you can't do that, reduce the number of threads to an absolute
minimum, reduce the cache to max 1G, and reduce the stack size until
it's stable.
