Speaking as another SP, we usually found that the customer had some *very old* 
code that typically contributed to this type of thing being seen.  We would end
up putting the "dont-cap" on customers sessions until they could upgrade their
devices to modern code.

Typically a SP is upgrading code to work around some known catastrophic defect
set, or for new hardware support.  Communicating with customers during a maint window
to find out what hardware/code they are running could be a problem.

Try to let them know what you are using so they can figure out the impact.
