Good day, We ran into an issue this morning with some caching DNS servers. One of the zones we heavily rely on was having DNS issues, which appears to have been causing very slow responses to us. The servers in question handle about 500queries/second.
These particular servers are configured with "recursive-clients 5000", which we thought would be sufficient. However, before we even reached 5000, the server started boinking because of "socket: too many open file descriptors" errors in syslog. So, the question is, do we need a 1:1 mapping of fle descriptors to max queries, + overhead for named? From reading, I see that a socket uses a file descriptor, so my assumption is yes, but I wanted to check with Those Who Are Wiser Than I before I write a change ticket to get these things fixed. If I do need to allow more file descriptors, what is the best method to ensure that the named process has an appropriate number? Thank you very much for your help, E. _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
