Hello, I have the following issue, when I'm calling interprocess_condition.timed_wait with time equals to boost::posix_time::pos_infin it has different behavior under linux and under windows. Under windows it is similar to interprocess_condition.wait, but under linux it fails with assertion here: file boost\interprocess\sync\posix\interprocess_condition.hpp: inline bool interprocess_condition::do_timed_wait (const boost::posix_time::ptime &abs_time, interprocess_mutex &mut) { timespec ts = detail::ptime_to_timespec(abs_time); pthread_mutex_t* pmutex = &mut.m_mut; int res = 0; res = pthread_cond_timedwait(&m_condition, pmutex, &ts); assert(res == 0 || res == ETIMEDOUT); return res != ETIMEDOUT; } I don't know which behavior is better, but I suggest it should be the same for both OSes. Best Regards, Sergei
