Tuesday, March 09, 2010 10:18:36 AM Internal Error nhiPoller[Net] Pgm nhiPoller[Net]: Expectation for 'isFastElement ()' failed (in file
../plrConfig.C, line 375). (cu/cuAssert)
This message will occur if you have a parent and child element with incompatible poll rates, such as a fast polled parent and a normal polled child. The constraint checker in the cfgServer should fix any such problems automatically when you modify the elements, 'unless' the nh_element table in the db has been manually modified.
You should be able to determine which element is a problem by looking at the list of fast polled elements and check the corresponding poll rates of the parents and their children.
