We've some servers in linux and those servers get hang(stuck) but not stopped. So, how can I deal with those servers. It's not clear what's the cause of this stuckness. Any guidance will be appreciated.

Care to provide more information? Like every bit of where you're at, what you've checked, what logs say, what's just happening before, what should happen but isn't etc? This is a server, so you're some class of sysadmin, right?

I don't fancy outlining all the possible reasons why things might get stuck.

Man, server hang-ups are always a headache. I've faced similar issues in the past. If it's not giving you any error messages, it's kinda like flying blind. Have you tried looking at the logs just before the hang occurs? Could help pinpoint if it's a software issue or something else.

Another route is to use monitoring tools to see if it's a resource bottleneck. If all else fails, sometimes a hard reboot might be the only way to get it back online, but I know that's not ideal. Would love to hear how others are tackling this issue.

You're a spammer; your spam link in your only other post has been reported. And if you actually read the post here, you'd see they were already asked about logs and to provide more details.

I would find a way to confirm it's not just the network hanging. Reason I say that is I have a server that will randomly lose the entire network stack, but the server itself is still running. My "fix" is a script that runs every 15 minutes that tries to ping a bunch of local servers and then google. If every single one of those fails it will reboot the server. It's an automation server so I can tell it's still running because the automation stuff still happens, it's just that I lose network connectivity to it. It's a really weird issue since it happens maybe once or twice a year only so it's very hard to troubleshoot.


If the whole server is completely hung and it's doing this often enough I would maybe hookup a monitor to it and run something like "dmesg -w" and wait to see if it catches anything in the last moments before it hangs. That's assuming it's not crashing to the point that it loses display.
