On one of my servers Named is timing out when the server load is high. On other servers with the same amount of zones I do not have this problem. The load can be at 50 or at 100 but Named still works... However, on this server named even times out if the load is around 10 which is a high load of course but not too high for Named to work IMHO. If I log in and enter "dig @localhost localhost" it waits for a few seconds...then times out. Then after around 1 or 2 minutes it is working again.
Does anyone have an idea what I could do to prevent this from happening ? I already looked at /var/log/messages but didn't find error messages from named.
