Anything useful in there? It's been awhile since I looked at a strace of named under load, but seem to recall this being normal for non-blocking sockets...take that with a grain of salt, it's was long ago when I went looking for EAGAIN/ENOENT on google. :-) I'm sure someone from ISC can provide a lot more insight into "normal" operation. Aside from logs, how does rndc status look under load? Do you have anything like cacti or graphite pulling numbers out of statistics output, to possibly spot any trends? What options are you running in named.conf, and what is the BIND version? _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
