Witango-Talk: a strange error

[Atrix Wolfe]

hello, in our error logs were finding an error ive never come across while debugging   format error: warning COL: input text invalid, text not formatted   after it does this error, it seems to "hang" the server for a while and could be the cause of some server issues weve been having lately.   has anyone ever seen this before or know what might cause it?   Thanx for the help (:   -Atrix
