I mistakenly used a limited server as an iperf server for 5000 parallel connections. (limit is 1024 processes)
Now every time I log in, I see this:
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
Then, I try to kill them, but when I do ps, I get this:
-bash-4.1$ ps
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
Same happens when I do a killall or similar things.
I have even tried to reboot the system but again this is what I get after reboot:
-bash-4.1$ sudo reboot
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash-4.1$
So Basically I cannot do anything. all the commands get this error :/
I can, however, do "exit".
This is an off-site server that I do not have physical access to, so I cannot turn it off/on physically.
Any ideas how I can fix this problem? I highly appreciate any help.
