Hello.
While working on rtorrent OpenIndiana component I've seen stange
sporadic application hangs. Application becomes unresponsive and can't
be killed without reboot.
After some debugging I've found that it actively uses mmap/munmap
functions and sometimes hangs in munmap system call.
It enters in munmap() with m_ptr=FD213000 m_end=FD413800 and never
leaves it.
Dtracing also showed that in this case munmap::entry probe is hitted,
but munmap::return is never reached. How can I debug this further?
