что есть bt?
Всё слАмалось, да. Ничего не работает, кроме килла, а он процессов не видит. Или не те прибиваю. ps тоже не работает с той же ошибкой.
Ошибка характерна для OpenVZ. но чтобы для фри..

Можно вообще что-то послать фре через putty, чтобы выполнить принудительную перезагрузку? Вроде SysRq в лине.

Reproduce «no more processes» error

For academic purposes I would like to reproduce the error message «no more processes» on my bash terminal. For example:

$cp file1.txp file2.txt bash: no more processes 

This means the system is out of processes. Try running your command repeatedly while running the «bash fork bomb» in another window: google.com/search?q=bash+fork+bomb

1 Answer 1

If you want to reproduce that error, you can probably just start a fork bomb with the first parent exiting to get you back to your shell:

You’ll probably want to ensure that your system applies a process limit before doing this otherwise you might just freeze the machine rather than get a shell where you can type stuff in and have it report that you don’t have anymore processes left to do anything. You’ll want to check out how many processes you are using normally first to figure out what limit to set.

In FreeBSD, you’ll edit /etc/login.conf and change the maxproc on default and then set it to unlimited on root .

In most Linux distros, you’ll edit /etc/security/limits.conf and add a line at the bottom that looks like this: * hard nproc nnn , where nnn is the number of processes.

Then make this simple fork bomb and run it:

#include #include int main() < int pid; pid = fork(); if (pid) < // parent exit(0); >else < // child while (1) < fork(); >> return 0; // we'll never get here >

• HP-UX: maxuprc, nfile
• Linux: nproc, nofile
• Solaris: project.max-lwps, process.max-file-descriptor

Linux Error Solution, No More Process Problems



If you have a Linux bug, then this guide may help you.

Approved: ASR Pro

If you do get a No Processes error, there may not be a built-in corruption command in the shell. Many shells do this, including Occasion and csh. (For example, your bash might be in / usr / local / bin.) If you try to get a “Process not created” response, your echo command will probably fail.

If you get the No More Processes error, your shell should indeed have a built-in kill command. Many shells do this, including bash and csh. (For example, perhaps your bash is usually located in / usr / local / bin.) However, if users get a response like “No new process”, your echo command is probably not integrated.

Is there a maximum number of processes in Linux?

As suggested by Ninefingers. For completeness, you can change it temporarily, if you wish, by writing to / proc / syskernel / pid_max along the way, or permanently by adding: to /etc/sysctl.conf. 4194303 is the maximum limit for x86_64 in addition to 32767 for x86. A short answer to a separate question: The number of possible processes in a Linux system is UNLIMITED.

Now, if users want to reproduce this bug, you can probably just throw the fork bomb by killing the first parent to get the buyers back into your shell:

You probably really want to make sure your system enforces the decision limit before you run out of processes to take any action. First, you should check most of the processes you normally use to find out what the limits and settings are.



On FreeBSD, edit /etc/login.And conf , change my maxproc to default , then set this tool to unlimited to root .

On most Linux distributions, edit /etc/security/limits.conf and add below website that looks like this: * hard nproc nnn where nnn is the sorting process.

 #include #include int main () int-PID; pid is equivalent to fork (); if (pid) // parent Output(0); Besides // Child during (1) Fork(); return 0; // we will never go here
