GFAL2 is not doing any kind of file descriptor handling behind the scene (AFAIK). Now the epoll_create1 is called with EPOLL_CLOEXEC but I don't thing the close-on-exec is subject to race conditions. Any thoughts? It's been a while since I thought about this but I think gfal2 was only involved because it happened to be the way XRootD was being loaded. I could probably have reproduced it with just `xrootd` and `fork` but I stopped once I understood the problem well enough to open this issue. -- You are receiving this because you are subscribed to this thread.
