this is on r292778 and ports r404859, amd64 all compiled from head; just start: $ libreoffice and exit from the file menu or with Ctrl-Q; the proc haengst forever; a ps shows: 15970 3 I+ 0:00,05 /usr/local/lib/libreoffice/program/oosplash 15985 3 I+ 0:00,85 /usr/local/lib/libreoffice/program/soffice.bin --splas Ctrl-C end the proc.
I watched with truss(1) what the soffice.bin proc is doing after receiving Ctrl-Q: it's closing all filedescriptors, trying to send some SHUTDOWN into some socket and hangs for ever in this calls: close(10) = 0 (0x0) munmap(0x800769000,670842) = 0 (0x0) close(9) = 0 (0x0) munmap(0x80075a000,57362) = 0 (0x0) close(7) = 0 (0x0) lstat("/usr/home/guru/.config/libreoffice/4/.lock",{ mode=-rw-r--r-- ,inode=18629985,size=137,blksize=32768 }) = 0 (0x0) unlink("/usr/home/guru/.config/libreoffice/4/.lock") = 0 (0x0) shutdown(8,SHUT_RDWR) ERR#57 'Socket is not connected' close(8) = 0 (0x0) unlink("/tmp/OSL_PIPE_1001_SingleOfficeIPC_78ab5adf6fd91c539d475f9513c71017") = 0 (0x0) _umtx_op(0x800736080,UMTX_OP_WAIT_UINT_PRIVATE,0x0,0x18,0x7fffdf5f8e58) ERR#60 'Operation timed out' _umtx_op(0x800736008,UMTX_OP_WAIT_UINT_PRIVATE,0x0,0x18,0x7fffdfffded8) ERR#60 'Operation timed out' _umtx_op(0x800736080,UMTX_OP_WAIT_UINT_PRIVATE,0x0,0x18,0x7fffdf5f8e38) ERR#60 'Operation timed out' munmap(0x8021fe000,4096) = 0 (0x0) _umtx_op(0x800736008,UMTX_OP_WAIT_UINT_PRIVATE,0x0,0x18,0x7fffdfffded8) ERR#60 'Operation timed out'

the problem is caused by closing the socket file descriptors in one thread, while another thread is still in accept(2) on the same socket and this is not canceled in the OS; the same is true for pipes; I'm attaching patches for this to be placed in editors/libreoffice/files;

I can reproduce the problem with the systray icon disabled and the patches fix it. The upstream patches only change the behaviour for sockets, not pipes. Was there still a problem if you only changed it for sockets?
