XF 2.1 Push Notification Errors

[OakleyForum]

Any ideas what's causing this? Seeing hundreds of these notifications over the last few days:

Server error log

Temporary Server Network Glitch/Issue.

 

[OakleyForum]

Interesting, They seem to be occurring periodically over several days/weeks now. So we're saying there is a temporary server glitch every hour or two?
