jhsdb can't attach the java process in MacOS Monterey

macOS Monterey version is 12.5
and jdk version is 11
I was going with sudo jhsdb jmap --heap --pid xxxx to analyze java process. Then I got the error followed
Password:
Attaching to process ID 47413, please wait...
ERROR: attach: task_for_pid(47413) failed: '(os/kern) failure' (5)

The server is a RHEL with WebSphere 9.0.5.5 and java openjdk version "1.8.0_292"
The application is developed so it takes a message from a message queue and processes them. The message queue being used is IBM MQ 9.1.1.0. The application is taking the messages but not processing them correctly. The error is presenting on startup and also on execution.
Any guidance would be much valued.

It looks like the AppServer is using OpenJ9 while your application is being compiled with openjdk 1.8. Perhaps you are getting mismatch in the WAS ManagementFactory. Try "ps -fea" and check the jvm being used.

It was resolved by installing and configuring java JRE version 1.8 at Websphere execution level.

jvisualvm: Software caused connection abort: socket write error

When I want to profile a java programm started from eclipse with jvisualvm 1.3.8 I get the error message within eclipse console:

This also happens when I start the program without eclipse (java -jar ...) from command line console. I tested jvisualvm from JDK 1.8.0_20 and downloaded the newest version 1.3.8. Here is the stacktrace:

After this the port 5140 is opened by my application to be profiled. I googled a lot and could not find any help with this. I also wrote another simple program and the error occured as well.
What can I do?

I've encountered this a few times. What OS platform are you running this on? Windows? or *nix?
On Windows, you'll almost certainly need to run your Eclipse and/or the jvisualvm using Admin privs...I typically set up a command prompt, Run As ... Administrator.
On Linux, you'll need to be running Eclipse and/or jvisualvm as either root or with an account that has privs that match or exceed the account running the pid you are trying to monitor.

This is definitely a firewall issue. Most likely you will not have rights to disable your firewall if an OS is not asking you (Windows). In my case I had eventually ran the application on another box where I had rights to allow JVisualVM to connect to my application.

jstack unable to print java thread stacks from Windows crash dump

jstack requires a java VM process/core!
I've double checked that:
I'm running the same version of java as the system that the crash occurred on
The bitness of Windows (32) matches the system that the crash occurred on
jvm.dll is in the path
windbg is installed
I get exactly the same error if I try to extract a java heap dump using jmap.
Does anyone know what could be going wrong?

I don't know how to solve the problem. Please, help me, guys :)

You don't have permission to write to /var/log, which is to be expected. You'll need to run Cassandra as sudo or create the directory yourself with the proper permissions.

config/cassandra.yaml - contains paths to all folders required by Cassandra. Change those paths to place where your user has write access so that you do not need to run it as sudo.

I think a potentially less intrusive solution for working on local dev machines is not to mess with root permissions at all. Just change the log locations to anywhere you want by editing the log4j properties file in the <cassandra_install_dir>/conf directory.
