Error connecting to process: sun.jvm.hotspot.debugger.DebuggerException: cannot open binary

Question

When I use jmap to get process information, I get this error:

$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 solved one more error ( DebuggerException: Can't attach to the process) by updating kernel.yama.ptrace_scope = 0.
