I have the following shortened rules in my ::preroute chain: SUBSCRIBED? PASS. When a local user goes offline, it's triggered on the presence-unavailable going out via s2s, causing this stacktrace (because the user is offline, their roster is unavailable and thus mod_firewall assumes that the recipient is the local user): Mar 20 07:37:04 c2s5569b5f71820 debug Received[c2s]: <presence type='unavailable'> Mar 20 07:37:04 mod_firewall::preroute debug Chain "user/pass_acceptable" accepted stanza (ret false) Mar 20 07:37:04 c2s5569b5f71820 debug Presence without caps received, skipping Mar 20 07:37:04 mod_firewall::deliver debug Chain "user/pass_acceptable" accepted stanza (ret false) Mar 20 07:37:04 mod_firewall::preroute debug Chain "user/pass_acceptable" did not accept or reject stanza (ret nil) Mar 20 07:37:04 rostermanager debug load_roster: asked for: contact@xmpp.jp Mar 20 07:37:04 rostermanager debug load_roster: loading for offline user: contact@xmpp.jp Mar 20 07:37:04 storagemanager error Failed to load storage driver plugin internal on xmpp.jp: unknown-host Mar 20 07:37:04 storagemanager warn Falling back to null driver for roster storage on xmpp.jp Mar 20 07:37:04 mod_c2s error Traceback[c2s]: /usr/lib/prosody/core/storagemanager.lua:167: attempt to index field '?'

Thanks for the report. Did we decide if this is a bug in rostermanager or a misuse of the API by mod_firewall?
