* Ed LaFrance: > Thanks for chiming in. Named is PID 8349 in my case. Here's a snippet > of the output from strace:
> [pid 8351] send(3, "<30>Nov 11 13:07:25 named[8349]:"..., 107, > MSG_NOSIGNAL) = 107 <0.015232> > [pid 8353] send(3, "<30>Nov 11 13:07:25 named[8349]:"..., 103, > [pid 8353] <... send resumed> ) = 103 <0.015034> This look like syslog logging is the culprit, each syslog message takes 15ms to complete. There could be several causes: syslogd is logging synchronously to disk (doing an fsync after each message), something else in the system is producing an extremely large number of messages (syslogd is single-threaded), or there is a request loop where writing out the syslog message for each reverse DNS request requires itself a reverse DNS lookup. You should also check if named is expected to log this many messages in the first place. You can pass "-s 200" to strace to see more of the logging message, so this should help to identify what's going on. I don't think this has got anything to do with the particular BIND version you use. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
