It is a log mesage of level "error". If you set in your ejabberd config file the option loglevel to 1, then log messages of that category are not printed.

A more fine-grained solution:
1. Download ejabberd source code of your version
2. Apply this patch, so the error message doesn't display the call arguments:

--- a/src/eldap/eldap_pool.erl
+++ b/src/eldap/eldap_pool.erl

                {'EXIT', Reason} ->

3. Compile ejabberd. Well, in fact you only care about compiling eldap_pool.erl
4. When you get the binary file eldap_pool.beam, copy it to replace the old one
5. Restart ejabberd, or reload that file at runtime using WebAdmin.
