I am cluless about JSTACK is being unable to get thread dump of a process. It is retuning errors "java.lang.RuntimeException: Unable to deduce type of thread from address... "

I tried below commands:

$ sudo bin/jstack   42846

Answer 1

Actually, it worked when I run the jstack command as the owner of the process. I was running jstack as root user and the process I was trying to take thread dump was a Cassandra DB process. Owner of the process was "cassandra" user and when I run the "jstack" command from "cassandra" user, everything worked.

But the jstack error output should have been able to indicate that issue, unfortunately it spews out something different.

Another option might be missing debuginfo on CentOS, I've solved it by

#debuginfo-install java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64
