i've looked into that but I'm new to ulimit so perhaps i'm missing something. first, about the machines. I'm running on ec2. for these tests i've been just running on a single machine. I've tested para & HVM architected machines seperately. logged in via ssh, command line: $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 59623 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 59623 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited when i condor_ssh_to_job: ulimit -a core file size (blocks, -c) 1317074 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 59623 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) unlimited cpu time (seconds, -t) unlimited max user processes (-u) 59623 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited SO there are differences (core file size) but not max memory size, data seg size, or virtual memory. I turned on wine debugging. This causes the process to runs in slowmotion. So we can examine /proc/pid/limits for the wine process: root@master:/proc/11457# cat limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size unlimited unlimited bytes Max core file size 0 0 bytes Max resident set unlimited unlimited bytes Max processes 59623 59623 processes Max open files 4096 4096 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 59623 59623 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us From within the condor job - from stata, which launches the wine process via stata's shell command): SO it would appear there is no applicable linux memory limit. any additional thoughts? jason On Mar 28, 2012, at 3:47 PM, Ian Chesal wrote:
