Hello, have you tried the suggestion from Charles in the other response? It can help figuring out where the problem resides.
Now, from C point of view, I would need the following output from gdb of the core file: frame 0 p *reason frame 1 p *worker p *current_job I would also need to know the modparams for dmq and other dmq_* module, plus the list if modules for which you enabled dmq (eg, htable, dialog, presence, ...).
