So, what I propose at this step: - Restart my strace, this time using '-e trace=desc' (Trace all file descriptor related system calls.) - Choose to focus on a single descriptor; when I passively notice that '19' has been reused a couple of time, stop the trace. That should give me a smaller trace to analyze. > Zbyszek -- Brian Reichert <reichert@xxxxxxxxxxx> BSD admin/developer at large _______________________________________________ systemd-devel mailing list systemd-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/systemd-devel
