Hello,
One of our customers reports an error in the log file of our UA server on a cyclical basis. I’ve copied a short extract from the log file below.
Nothing else seems to be happening, but the log is getting much bigger, and neither we nor our customer would want to miss out on a potentially serious problem.
Is the source of this exception known, and is there anything I can do to stop it happening?
We still use SDK 7.5.1 build 805.
Thank you in advance
Denis

That is “as designed”, so unfortunately, you cannot do much about it. The exception is handled in the code and you shouldn’t need to log it.
It is caused by the client defining a short timeout for PublishRequests, which passes faster than there are update notifications to send back to the client.
