Are RabbitMQ messages needed

We ran into some disk issues while trying to upgrade from 11.3 to 11.4.  The directory that was filling up was Prognosis\Server\Configuration\Messaging\RabbitMQ. I noticed in that directory that there are hundreds of thousands of files called MnesiaCore.rabbit@<servername>.  Do these need to be kept for any reason or can they be safely removed without breaking functionality?

Re: Are RabbitMQ messages needed

Hello Joshua, 


RabbitMQ messages are needed only if you are using Skpe for Business in your enviorement. If this is not a core product being used, you can turn off the RabbitMQ services to disable this function.  See screenshot below:

The second part of your question in regards to the MnesiaCore files, these are core dump files. If Mnesia malfunctions, system information is dumped to a file named MnesiaCore.Node. These can be deleted out or they can be zipped up and backed up to another location off the drive.

You can set the core directory with the configuration parameter:
 erl -mnesia core_dir Directory  
If the above information doesn't resolve the issue, I would recommend opening up a support case with an IRfax to review the logs.

How to create an IRFAX in Windows:

  1. Using File Explorer open the directory where Prognosis is installed and navigate to the \Prognosis\Server\Configuration directory.
  2. Double click the irfax.bat file. A command window will open and run irfax.bat. Once the window returns to a command prompt or closes the irfax is complete.
  3. A .zip file will be created in the same directory using the following naming convention: irfax-<ComputerName>-<DateTime>.zip.
  4. Upload the .zip file directly to the Support Case or send the file via email.
Please let me know if you have any further questions.
