[Sajawal]

Hi,

I'm facing an issue of "Segmentation fault" while ssh a server from my cPanel (command line), can anybody help me on this issue.

So you are trying to SSH to another server from your cPanel terminal and getting segmentation fault?
Can you make a screenshot please?
Does other commands like yum update or w or ps aux etc.. works correctly?
Do you have enough space on the server?

This is a issue when cPanel's Fork Bomb Protection is enabled.

Fix: Log into WHM as root, click "Shell Fork Bomb Protection" and disable that feature, and things should continue to work fine.

Hi, "Shell Fork Bomb Protection" status is disabled on my server.

Hi, "Shell Fork Bomb Protection" status is *already disabled on my server, and the issue is notresolved.

Hello! Could you get the information Andrew asked for?

Do you have enough space on the server?

The following article might help as well.

Please note that the chances are incredibly likely that this issue is not related to cPanel and contacting a qualified systems administrator would be suggested.

When you ssh the first time it shows connection refused and when you SSH second time it shows segmentation fault. Do you SSH to the same or different servers? Is there any difference in the commands you are using? Do you see segmentation fault in "dmesg" as well? what is logged in to /var/log/messages file?

The first time port was not defined which is why the connection refused message received and there are no logs in /var/log/messages and "dmesg" about these.

It looks like the quote broke in my last response, apologies. Would you be able to contact a sysadmin to review any relevant core dumps? These issues are best reviewed by a systems administrator.
