Undata acting strange

The last few days during lights out my undata has been sliming up across almost the entirety of the coral.  At first I thought it was possibly spawning, but now that it has done that four days in a row that would seem unlikely.  Seems like it is annoyed.  I don't see anything on it, but my cleaner shrimp like to hang out by it at night so it is possible they are climbing on it at night.  They move away to another area during lights on.  All my parameters are good (Alk 7.4, Ca 390, Mg 1275).  All my acros seem happy as can be.  Has anyone seen this before?
