Hanging application

Hi all,

I have a problem with a hanging multithreaded C++ application (build with SunStudio10). To find out where it hangs, I want to debug it, but in the debugger I can not reproduce this behaviour. Is there a possibility to force the application to write a corefile when it hangs, that give me a snapshot of the current process state (callstack of every thread)?

regards

Arno

You can force a core file generation with gcore when the application hangs.The pstack tool (piped to c++filt) may also give you some hints regarding the cause of the problem, without generating a core file.

Instead of gcore'ing your process you might want to run dbx separately and 'attach' to the process.You'll get your hang in dbx with all the debugging/inspecting functionality ready (not just call stack).regards,__Fedor.

Thanks a lot!

A last question to this:Is gcore and pstack available on all Solaris versions also without development tools installed?

Hard to say, but if you don't have pstack on any of your systems, you can find it in SUNWesu package on installation CD/DVD; gcore comes from SUNWtoo.
