LAN sometimes 'hangs', mysql takes several seconds to connect
I have several web+db servers connected.If I log into one of the DB servers and do a 'mysqladmin' locally it always only takes a couple milliseconds to complete. If I do it from an other server it's usually fast, too but 1 out of 10 requests take 3-4 seconds to complete (and then it shows the mysqladmin process completed in '0 seconds').
I have skip-name-resolve in my.cnf, ping with default or 8k packet always shows the same speed.
Any ideas how to debug/fix this?
