Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Attempt to join a room using any client
2. Wait for nothing to happen
3. See the server logs for traceback

What is the expected output? What do you see instead?

I see a crash.

What version of the product are you using? On what operating system?

OS: Debian 7 64-bit
Prosody: f2a7ad099e01

(I did a `hg pull -u`and rebuilt + restarted Prosody)

Please provide any additional information below.

Hi, thanks for the report!

This is technically not a Prosody bug. It's caused by mod_muc_limits from 
prosody-modules, which is not compatible with Prosody's trunk development 
branch.

The immediate solution is to either unload mod_muc_limits, or use a stable 
version of Prosody until mod_muc_limits is updated to work with our latest 
changes.
