Hi, our server went down because of only one user that uses Dino. We have a lot of "Failed to enable smacks: Stream management is already enabled" lines in the logs. We're wondering if this could be related to this: https://github.com/dino/dino/issues/271 I see this also: Mar 10 19:51:12 mod_bosh error Traceback[bosh]: /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:164: attempt to get length of local 'queue' (a nil value) stack traceback: /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:164: in function 'request_ack_if_needed' /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:645: in function '?' /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) /usr/lib/prosody/modules/mod_csi/mod_csi.lua:15: in function '?' /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) /usr/share/lua/5.2/prosody/core/stanza_router.lua:143: in function 'dispatch_stanza' /usr/lib/prosody/modules/mod_bosh.lua:338: in function 'func' /usr/share/lua/5.2/prosody/util/async.lua:127: in function </usr/share/lua/5.2/prosody/util/async.lua:125> stack traceback: /usr/share/lua/5.2/prosody/util/async.lua:215: in function 'run' /usr/lib/prosody/modules/mod_bosh.lua:482: in function 'cb_handlestanza' /usr/share/lua/5.2/prosody/util/xmppstream.lua:188: in function </usr/share/lua/5.2/prosody/util/xmppstream.lua:165> [C]: in function 'parse' /usr/share/lua/5.2/prosody/util/xmppstream.lua:288: in function 'feed' /usr/lib/prosody/modules/mod_bosh.lua:136: in function </usr/lib/prosody/modules/mod_bosh.lua:117> (...tail calls...) /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) /usr/share/lua/5.2/prosody/net/http/server.lua:282: in function 'handle_request' /usr/share/lua/5.2/prosody/net/http/server.lua:126: in function 'func' /usr/share/lua/5.2/prosody/util/async.lua:127: in function </usr/share/lua/5.2/prosody/util/async.lua:125> Mar 10 19:57:46 c2s55b241990e50 error Traceback[c2s]: /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:164: attempt to get length of local 'queue' (a nil value) stack traceback: /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:164: in function 'request_ack_if_needed' /usr/lib/prosody/modules/mod_smacks/mod_smacks.lua:645: in function '?' /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) /usr/lib/prosody/modules/mod_csi/mod_csi.lua:15: in function '?' /usr/share/lua/5.2/prosody/util/events.lua:81: in function </usr/share/lua/5.2/prosody/util/events.lua:77> (...tail calls...) /usr/share/lua/5.2/prosody/core/stanza_router.lua:143: in function 'core_process_stanza' /usr/lib/prosody/modules/mod_c2s.lua:295: in function 'func' /usr/share/lua/5.2/prosody/util/async.lua:127: in function </usr/share/lua/5.2/prosody/util/async.lua:125> Here are our setup info: Prosody trunk nightly build 1405 (2021-02-25, f7704f987439) Lua version: Lua 5.2 LuaRocks: Installed (2.4.2) Backend: epoll LuaDBI: 0.7 LuaExpat: 1.3.0 LuaFileSystem: 1.6.3 LuaSec: 0.7.1 LuaSocket: 3.0-rc1 modules_enabled = { "roster"; -- Allow users to have a roster.

What revision of prosody-modules is this? The line number for mod_smacks doesn't match the current code, but would match before https://hg.prosody.im/prosody-modules/rev/5234d0c8883d which likely fixed an issue just like this.

You're right, I checked again, and this seems to be fixed. Sorry!
