Hi, Please provide details on the kind of error.
Is the "push server exception" an exception thrown by your tool or is it the PushServerException that is thrown by some of our client SDKs?
In the latter case, what is the associated message?
Can you specify the exact time of one occurrence of the issue, to help us browsing in the log?

I see you are writing on the ".NET Adapter API" forum, but can you confirm that your tool is actually a client?
Do you also notice adapter side problems?
The log shows that there are delays in answers by the Remote Adapter to subscription requests.
After a timeout, the Server gives up, hence the subscriptions, even if finally successful, will never yield any data.
Can this be a source of issues for you tool?
