Error attaching to process: sun.jvm.hotspot.debugger.DebuggerException: cannot open binary file
Solution 1
I faced the same issue, however when I su
'd to the correct user having the relevant permissions the issue went away.
Solution 2
Not directly related to the question asked. But, I encountered a similar error while using the jstack command while taking the thread dump of a java process. Let's say the pid of the java process for which I wanted thread dump is 1234.
I had used the command jstack -l 1234 /home/users/a/thread-dump.txt
What I missed in the above command is the redirection operator(>). The correct version of the command is
jstack -l 1234 > /home/users/a/thread-dump.txt
Maybe it helps someone :)
Solution 3
This will also happen if you attempt to attach to an ineligible process so it's a good idea to reconfirm your pid.
For example, a friend of mine got this when they attempted to attach to the jps
process they used to search for eligible pids ;).
Solution 4
In our case, the java process was using .../JAVA_HOME/jre/bin/java
binary and the jmap process was using .../JAVA_HOME/bin/jmap
binary.
Once we changed java process to use .../JAVA_HOME/bin/java
binary, then the issue got resolved. We were able to run the jmap successfully.
Key is to use run the java process using JDK java binary instead of JRE java binary.

When I use jmap to get the heap info about a process, I got error like that:
$jmap -heap process_id Attaching to process ID process_id, please wait... Error attaching to process: sun.jvm.hotspot.debugger.DebuggerException: cannot open binary file sun.jvm.hotspot.debugger.DebuggerException: sun.jvm.hotspot.debugger.DebuggerException: cannot open binary file
OS: Ubuntu 14.04
I have solved another error (
DebuggerException: Can't attach to the process
) by updatingkernel.yama.ptrace_scope = 0

infraio almost 8 yearsYou mean it is a permission problem? But I run this command by the same user with the java process.

infraio almost 8 yearsAfter I restart my os, I start java process and use jmap again. There are no error. So it maybe permission probelm. But I am not sure about it.
