Audiocodes Mediant SBA Lyss error

Bumped into an error:

Log Name:      Lync Server
Source:        LS Storage Service
Date:          5/16/2017 5:54:02 PM
Event ID:      32071
Task Category: (4006)
Level:         Error
Keywords:      Classic
User:          N/A
Computer:     xxx
Storage Service had a failure while refreshing its calculation of DB space used.

DB Space Used Refresh Error. Object reference not set to an instance of an object.
Cause: The Timer task to refresh the DB space used value ran into an exception. This action will be retried and should auto recover.

Check event details. If problem persists, notify your organization's support team with the event details.

For the moment, not clear what causing it.

Option I consider for the moment are:

install latest Lync CU
install windows patches inside SBA (esp. .NET)
reset fabric
repair fabric
redeploy CS databases
repair SBA image and re-deploy from scratch

some relevant links I collected so far:

update: nothing really helped, we did completely redeploy from usb key.

Skype for Business/ Lync meeting expiration

Non-recurring meetings will expire in 2 weeks, if someone will opens it on 15th days  after meeting end date the URL will not work with error as below. I think 14 days is hardcoded, I’m not sure we can change it – refer to

To avoid the issue, create a recurring meeting, they will expire after farthest occurrence in the future.

About timestamp – note it is hardcoded to UTC time zone.
