 |
|
I'm writting an application server and need a fast way to check how
much memory by a process is used and do an emergency stop (aka
terminate) if the process is running wild.
Whats the best way to do this? |

man proc
The various fields of /proc/[pid]/statm should have what you want, once
you decide exactly what you mean by "how much memory is used". |

best way is to use well behaved software in the first place,
otherwise you can look in /proc/%d/status
where %d is replaced with the PID. |

Virtual memory or physical memory?

Physical memory, not adress space.
I want to write an application server for very low memory virtual
servers (~100 MByte total RAM)
and without swap space. |

Then 'ps' will tell you what you want. The 'RSS' column will tell you
how much physical memory it's using.

why not let the kernel do it for you using the setrlimit call? |
