Hello all.
Is it possible to increase "Max open files" parameter for working process ? I mean this parameter:
cat /proc/<pid>/limits | grep files
Thanks for your advices
Thanks for a link. But I've found it before asking :-) But the problem is to change parameter without stopping process (on runtime) and for process-wide.

@wako: It can't be done from outside the process (unless you're running one of the very latest development kernels, which is unlikely)

@caf: Thanks. This is exactly that I've wanted to hear.

As a system administrator: The /etc/security/limits.conf file controls this on most Linux installations; it allows you to set per-user limits. You'll want a line like myuser - nofile 1000.
Within a process: The getrlimit and setrlimit calls control most per-process resource allocation limits. RLIMIT_NOFILE controls the maximum number of file descriptors. You will need appropriate permissions to call it.

It seems that this is what I need. Can I set "setrlimit(RLIMIT_NOFILE,...)" for some outside process?

I don't know of any. If there is, I suspect you'll find it buried deep in some Linux-specific programming guide, because I can't fathom where else standard POSIX would put it.
