Thank you for reply, Igor!

But I guess the io_service thread is not blocked. Becase:
a) I have 2 threads. One pushes messages to queue. Second is
io_service.run() with timer that async_reads from socket and
async_writes the message queue to socket
b) program continues working. Async_read handler is called. Writing is
also completes (server, written in the same way - receives all data) +
timers "onTick"s are also invoked.

So, all IO is done within 1 thread and if it will be blocked then all
IO will stop, as I understand, but only async_write handlers are not
invoked.
Any thoughts are welcome.
It seems I've got very rare bug in my program))
