I can't reproduce this without seeing your configuration. Can you provide (attach as a file to the issue) your sanitized xmpp.conf ?

Can you also verify whether you had DEBUG messages enabled on the console and set to 5 or above? If not, please attach an Asterisk log with VERBOSE and DEBUG at level 5 or above demonstrating the same issue. (there may be other messages occurring around those ERRORs that we are not seeing.)

I attached the requested debug log

Thank you for the log, however I didn't find any good clues there.

I've still been unable to reproduce those particular ERRORs.

Please provide sanitized xmpp.conf,motif.conf if used, and any other relevant configs.

reproduce is quite easy, use xmpp for distributed device states, transmit some devicestate messages and do

module unload res_xmpp.so

the reason why we get this error, cfg in xmpp_pubsub_iq_create is null
debug:

[Feb 15 13:07:05] ERROR[30549]: res_xmpp.c:899 xmpp_pubsub_iq_create: cfg '(nil)'
[Feb 15 13:07:05] ERROR[30549]: res_xmpp.c:900 xmpp_pubsub_iq_create: cfg->global '(nil)'

I am able to reproduce these errors with Asterisk 11 SVN r381835, when setup with a config very similar to yours, except I'm connected to an OpenFire server.
