Looking at the module hit

Looking at the module hit history, it has received many commits in the last months: https://github.com/processone/ejabberd/commits/master/src/mod_delegation...

Take a look at the commits descriptions, in case they point to something relevant.

If you are able to reproduce easily the problem, and you can recompile and try different ejabberd git versions, then you could try "git bisect" to determine which exact commit broke the module for you. Ask me details if you are interested in "git bisect" but you don't know how to use that.
