_umtx_op -1 errno 60 Operation timed out using 7.0-BETA4

[Imri Zvik]

Hi,
I've tried using libthr with bind 9.3, but after a while, bind stops
working (that is, responding to queries - the process is still alive)
and I can see the following with ktrace:

1667 named    CALL  _umtx_op(0x81a6304,0x2,0x17,0,0xbf5fae20)
1667 named    RET   _umtx_op -1 errno 60 Operation timed out

With libpthread everything works fine... 


It happened with 6.3-STABLE too.

Any ideas where to look next?
