I've used the gem5art and slightly modified the runscript not to run spec benchmark and run /bin/bash instead. It seems that this error has happened a while ago and issued in here. It seems that this problem has been fixed by the gem5 v19 but got the same error code. Could anyone explain why this error happens and how to fix it?

I'm new to kernel debugging, I'm trying to analyze the vmcore file using crash tool on RHEL 7. I'm trying to open the dump with below command.
crash /lib/debug/lib/modules/3.10.0-1160.80.1.el7.x86_64/vmlinux vmcore
but tools fails to load the vmcore with below error:

I'm not sure this the vmcore file issue or crash tool issue. Can someone please help resolve this issue.
Thanks in advance
Problem
I re-installed my server system.Before then, I can use remote-ssh normally.However, I can't use remote-ssh to connect to my server anymore.But I can still use ssh directly to connect to the server.
I suppose it managed to get into the system but somehow it broke down.
The error log is below:

Tried
I tried delete the know_hosts file from host, re-install the remote-ssh plugin, but can't work
I am pretty new to remote-ssh, hope can give me more detailed solution.
Thanks :)
I downgraded remote-ssh.Then I changed my default shell into zsh and upgrade remote-ssh.It began to install '.vscode-server' file again and magically it worked.

i use otp_win64_23.2 and rabbitmq-server-3.8.12
Go to windows services and look for RabbitMQ. Right click on it and stop the service.
Restart the RabbitMQ server in an administrator mode. This worked for me.
I'm trying to start my rabbitmq server using command:sudo rabbitmq-server on ubuntu 20.04 but it crashes.I have absolutely no clue whatsoever as to what I should do.

Any help would be great
It's pretty simple. Just needed to look at the logs. killed the process at the port number "25672" and restarted the rabbitmq server.
when running GEM5 X86 in SE mode, I am trying to run bzip2 from SPEC2006, at first it was failing because it says it can't run dynamic execution so I compiled it with -static flag.
now I get this error:

I am running gem5 on ubuntu 17.10.
I tried to find solutions in google but I didn't see any one referring to this problem, does anyone know how to fix the problem?
Please check your host machine configuration. Bzip2 does not work in a 32-bit machine. My desktop is dual core have 32-bit X86 architecture, I tried to run bzip2 it had shown same error.
