dtrace discuss - May 2006 - Dtrace to detect deadlock

Hi,
  I am facing a Nested Monitor Deadlock situation in my java application.
  Is there any DTrace script to detect Deadlock with its trace.
   
  Regards
  Karthik

Hi Karthik,

For Java SE 5.0 or less you can probably try to use dvm:::monitor-* 
probes from ''dvm'' provider
(https://solaris10-dtrace-vm-agents.dev.java.net/) to write Deadlock 
detection script.

If you use Java SE 6 then you can try to use built-in JVM probes 
hotspot:::monitor-*
(http://blogs.sun.com/roller/page/kamg?entry=built_in_dtrace_probes_in).

But probably more simple way is to use jstack or jconsole (which is part 
of Java SE 6) to detect deadlocks.
