When I'm testing some scripts or programs, they end up using more memory than anticipated. In that case, computer nearly halts due to swap space usage, and sometimes I have to press Magic SysRq+REISUB to reboot.

So, I was looking for a way to limit memory usage per script and found out that ulimit can limit memory. If you run it this way:

$ ulimit -v 1000000


$ scriptname

Then the new memory limit will be valid for that shell. I think changing the limit within a subshell is much more flexible and it won't interfere with your current shell ulimit settings.

note: -v 1000000 corresponds to approximately 1GB of RAM

ulimit -s 64

default stack size is 10M. This makes your multithread app filling rapidly your memory.

on my PC I was able to create only 300thread with default stack size.

Lower the default stack size to the one effectively used by your threads, let you create more.

ex. putting 64k I was able to create more than 10.000threads.

Obviously ...your thread shouldn't need more than 64k ram!!!

It is not uncommon to receive an error "Too many open files", this command allows you to change the limit for a user. This can be put into /etc/profile so that all users will have this change.
