I am using mnesia internal database to store data and i am querying mod_mam to retrieve room history after 100 concurrent chats ejabberd crashes and i get
Mnesia(ejabberd@localhost): ** WARNING ** Mnesia is overloaded: {dump_log,write_threshold}
in ejabberd.yml file i have set
mod_mam:
db_type: mnesia
default: always
should i use an external database or is it my configuration
