Deadlock in c++ on solaris

Question

please anybody suggest me how to check the deadlock on solaris with command pstack ?

Regards

Answer 1

Your question isn't really related to C++, but more the general multi-threading issue of a deadlock. When your program is running, get the pid and then in another xterm (or whatever you're using) you run pstack pid and check whether all threads are waiting for a mutex to be released. That's normally a pretty good indicator of deadlock.

Compare pstack outputs - if they are the same, and all threads are waiting for locks then you have a deadlock.
