I'm getting the error mentioned in the subject line ("Operation not
permitted (qpid/sys/epoll/EpollPoller.cpp:254)") when my c++ client
tries to connect to the broker.
I dug into the source code and here's the relevant excerpt:
244 PollerPrivate() :
245 epollFd(::epoll_create(DefaultFds)),
246 isShutdown(false) {
247 QPID_POSIX_CHECK(epollFd);
248 ::sigemptyset(&sigMask);
249 // Add always readable fd into our set (but not listening to it yet)
250 ::epoll_event epe;
251 epe.events = 0;
252 epe.data.u64 = 0;
253 QPID_POSIX_CHECK(::epoll_ctl(epollFd, EPOLL_CTL_ADD,
alwaysReadableFd, &epe));
254 }
(I assume that the exception was actually thrown by line 253 which
might be a two line macro or something of the sort).
I think it's relevant that I *only* get an error from epoll_ctl when
my client is running as a daemon (but at this point I'm not sure why).
Is this a known issue in the qpid c++ client with respect to
integrating it into daemon code (or just a known issue period)? Any
hints on where to look for conflicts between epoll_ctl and my daemon
code ?
