Description Chris Moller 2006-12-04 16:17:32 UTC
After running 

    ./TestRunner -r 10 frysk.proc.TestProcStopped 

in one xterm until it hangs, 

    fstack `pgrep funit-child` 

run from a second xterm also hangs, and stays hung even after TestRunner times
out.  Ctrl-C kills it.
Comment 1 Sami Wagiaalla 2007-09-13 15:38:43 UTC
pstack `pgrep funit-slave
returns nothing.

fstack `pgrep funit-slave`

fstack 'pgrep fstack'
returns this:
$$ fstack `pgrep fstack`
