If wineserver has no hook for limiting its own footprint
add a ulimit to the startup script or use a wrapper with one.
Look at ulimit -a for all the limits and the man page. There are
multiple shared commons resources that may apply.
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 20463
max locked memory (kbytes, -l) 32
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) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 20463
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
You can check limits on a running process too.
$ cat /proc/29906/limits
