Yes, we for now have a coredump (also see above for a GDB session with debuginfo, against 4.8.3 at the time). But there is only one `abort()` in function `XrdSys::IOEvents::PollE::Begin()`: ``` do {do {numpolled = epoll_wait(pollDfd, pollTab, pollMax, TmoGet());} while (numpolled < 0 && errno == EINTR); CPP_ATOMIC_STORE(wakePend, true, std::memory_order_release); numPoll = numpolled; if (numpolled == 0) CbkTMO(); else if (numpolled < 0) {int rc = errno; cerr <<"EPoll: " <<strerror(rc) <<" polling for events" <<endl; abort(); } ``` Please let me know what would need looking at. -- You are receiving this because you are subscribed to this thread.
