Not receiving emailed voicemail message

I am using elastix free pbx and recently I have stopped receiving the voice mail email. I am getting the messages on my phone just not the emails anymore. I have checked all vm settings in extension and general tabs and all is set up correctly with correct email address.
I have noticed some errors in my panel as follows:

Webserver - Error
SSH Server - Warning
Opp Panel - Warning

Your memory_limit, 16M, is set too low and has been increased to 100M. You may want to change this in you php.ini config file

(core.MEMLIMIT)

Not sure if any of the above errors are the problem however would anyone be able to help as to what the problem might be?

I am having the same problem after upgrading my system. I decided to restore my system from backup within Elastix but now one extension goes to busy when the outgoing message is supposed to play and I cannot get FreePBX to come up. Other than that everything is great :expressionless:
