自动杀死消耗过多内存或在linux上停顿的进程

我想要一个监视进程的"系统",并在以下情况下杀死所述进程:

该过程超出了一些内存要求

在某段时间内,该过程不响应来自"系统"的消息

我认为这个"系统"可能像监控过程一样简单吗？如何做到这一点的代码示例将是有用的.我当然不反对这个问题的完全不同的解决方案.

对于第一个要求,您可能希望研究使用ulimit或调整系统上的内核OOM-killer设置.

监视守护进程也存在于此类事物中. 上帝是最近的一个例子.

我编写了一个作为cron作业运行的脚本,可以自定义以杀死问题进程:

#!/usr/local/bin/perl

use strict;
use warnings;
use Proc::ProcessTable;

my $table = Proc::ProcessTable->new;

for my $process (@{$table->table}) {
    # skip root processes
    next if $process->uid == 0 or $process->gid == 0;

    # skip anything other than Passenger application processes
    #next unless $process->fname eq 'ruby' and $process->cmndline =~ /\bRails\b/;

    # skip any using less than 1 GiB
    next if $process->rss < 1_073_741_824;

    # document the slaughter
    (my $cmd = $process->cmndline) =~ s/\s+\z//;
    print "Killing process: pid=", $process->pid, " uid=", $process->uid, " rss=", $process->rss, " fname=", $process->fname, " cmndline=", $cmd, "\n";

    # try first to terminate process politely
    kill 15, $process->pid;

    # wait a little, then kill ruthlessly if it's still around
    sleep 5;
    kill 9, $process->pid;
}
