CX5500 - Calendar keeps disappearing

We have a CX5500 integrated with our Lync Server 2013 and Exchange 2013 environment.

When the phone boots up I see it login to Lync and the Calendar icon appears on the front display.

If I go offhook to make a call, when I go back onhook, the Calendar icon has disappeared.

When I go back onhook, I notice on the front display that Lync had logged out and I see the Lync signing-in message. Even after it has finished logging back in, the calendar never comes back. If I reboot the phone it will come back. Also I noticed that if I sign out from Lync from the web gui and sign back in the calendar icon will have returned for a while and eventually disappear again. We are running firmware 1.1.4.

 

When I enabled debug logging from the CX5500 web gui, I see the following entries that I think are relevant. I slightly sanitized some of the sensitve information (ip addresses/hostname)

 

 

0910111936|pgui |4|00|Received new credentials when the service has already authenticated, shutdown application so it can restart and retrieve the new credentials

Re: CX5500 - Calendar keeps disappearing

This may also be relevant.

At the same time this problem happens, I see the following event show up in the event log on the Lync Front End Server.

We have ran the csregistrarconfiguration command and set the maxendpointsperuser to 28 but this still shows up.

 

 

 

Event 14507, LS Protocol Stack
 
Cause:
At least one attempt to reference stale (non-existent or deleted) security association was detected.
There were 13 messages with signature that referenced stale (non-existent or deleted) security association in the last 2 minutes. The last one was this SIP message:

Cause: This could be due to users that utilize large number of devices (in excess of configured maximum), or due to connection refresh logic re-balancing remote users to a different director in a bank or a pool, or it could be due to an attacker.
Resolution:
None needed unless the failure count is high (>100). Check if number of allowed devices per user is too low for existing usage scenarios. Check your network for any rogue clients. Restart the server if problem persists.
