Question about program run out of memory

Question about program run out of memory

[梁晨]

hi,
I encountered such a problem when a program have some bug that it will ask for endless memory, until the system completely dead, I can only reboot it. Can I do some restriction of the max memory per process? Thanks!

Check out ulimit. It controls a number of parameters such as maximum  
memory size, core dump size, open file descriptors...

Sorry I can't pronounce or reproduce your name;

Have a look at /etc/security/limits.conf if the system uses pam.

Thank you, I tried "ulimit -Sv 1024000" successful, finally I wrote this line "* hard as 1024000" into /etc/security/limits.conf, so it can be apply when system booting.
