On version 0.10 I saw this kind of errors: Mar 08 15:08:46 bosh1677c504-debb-4e8c-896e-7221b324e508 info Authenticated as 204-uctest@localhost Mar 08 15:08:46 bosh1677c504-debb-4e8c-896e-7221b324e508 info BOSH client disconnected Mar 08 15:08:46 http.server error Traceback[httpserver]: /usr/lib/prosody/modules/mod_bosh.lua:270: attempt to compare nil with number stack traceback: [C]: in function 'parse' /usr/lib/prosody/util/xmppstream.lua:271: in function 'feed' /usr/lib/prosody/modules/mod_bosh.lua:136: in function '?' /usr/lib/prosody/util/events.lua:78: in function </usr/lib/prosody/util/events.lua:74> (tail call): ? /usr/lib/prosody/net/http/server.lua:239: in function </usr/lib/prosody/net/http/server.lua:180> (tail call): ?

I think this logic: if not rid or not wait or wait < 0 or wait % 1 ~= 0 then is good enough here, since: local rid = tonumber(attr.rid); local wait = tonumber(attr.wait); so attr.wait == nil => wait == nil

I think that's meant to be "if the wait attribute was included, but it was not a positive integer". It's optional, so it's fine if it's missing, but if it's included it should be an unsigned short integer, according to the non-normative schema.
