mnesia compatibility problem

Hello, everyone,

I have deployed a ejabberd cluster with ejabberd nodes . And It works fine, except that there is a error information in error.log.
2015-11-09 11:39:38.991 [error] <0.381.0> CRASH REPORT Process <0.381.0> with 0 neighbours exited with reason: {aborted,{no_exists,[caps_features]}} in gen_server:init_it/6 line 330

Anyone have any ideas?
