FAQ
Hi,

I believe the problem you're encountering is related to a bug with the
way we retrieve data for activities that do not have any attributes.
The problem was fixed in cm4.7.3 and if you upgrade to the latest and
greatest version fo cm (4.8.1) the problem should go away.

Thanks,
G.

Occasionally, while using the activities log viewer I will get a popup with
an AvroRuntimeException.

There does not seem to be any repeatable pattern to the issue. These errors
have increased in frequency the past few days.
