openoffice stuck in _umtx_op

[Mikhail T.]

Hello!

I'm trying to start OOo, and it hangs at start-up -- after popping up
its banner page.

ktrace shows the following, slowly repeating, sequence of events:

    [...]
     32726 soffice.bin CALL 
    _umtx_op(0x805d09060,0x8,0x1,0x805d09040,0x7fffffbfeef0)
     32726 soffice.bin RET   _umtx_op -1 errno 60 Operation timed out
     32726 soffice.bin CALL  gettimeofday(0x7fffffbfef70,0)
     32726 soffice.bin RET   gettimeofday 0
     32726 soffice.bin CALL  clock_gettime(0,0x7fffffbfef00)
     32726 soffice.bin RET   clock_gettime 0
     32726 soffice.bin CALL 
    _umtx_op(0x805d09060,0x8,0x1,0x805d09040,0x7fffffbfeef0)
     32726 soffice.bin RET   _umtx_op -1 errno 60 Operation timed out
     32726 soffice.bin CALL  gettimeofday(0x7fffffbfef70,0)
     32726 soffice.bin RET   gettimeofday 0
     32726 soffice.bin CALL  clock_gettime(0,0x7fffffbfef00)
     32726 soffice.bin RET   clock_gettime 0
     32726 soffice.bin CALL 
    _umtx_op(0x805d09060,0x8,0x1,0x805d09040,0x7fffffbfeef0)
    [...]

what's happening? `ipcs -a' does not show anything extraordinary and
there is nothing in syslog either...

The machine is running 7.2-STABLE/amd64 (as of Oct 25). Any ideas? Thanks!
