--- Comment #8 from Mike Jarvis <michael at jarvis dot net> 2011-06-10 21:26:59 UTC --- $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited Should I try changing any of these? stack size? Also, I don't really understand why you think it's a memory issue, when it is not getting anywhere close to using 8GB, my machine's physical memory, before it crashes. Although, I do understand that it's hard to guess what the problem might be when you haven't been able to confirm the bug on one of your machines.
