APIs updated for sending large attachments with MSGraph
Resolved in Pega Version 8.7
Sending mail using MSGraph was failing with the exception "Error during http request" when attachments were greater than 3MB. This was traced to changes made by Microsoft in the Graph API implementation which caused it to throw a runtime exception instead of the expected 413 status code and relevant message for the attachment size. To resolve this, an update has been made to ensure that any attachment larger than 3MB is sent via the Microsoft Outlook API.

Restored local blocking queue cache
Resolved in Pega Version 8.7
After update, it was not possible to bring up secondary VBD nodes after restarting. Investigation traced this to earlier work done to resolve a memory leak issue, in which stale entries for local blocking queues were removed from cache. This resulted in modifying the queue listener logic to use "cache.getQueueIfPresent(jobId)" instead of "cache.getQueue(jobId)". Because the listener was not creating the cache if it was not present and the cache which held the local blocking queue didn't have the entry for the current remote execution job ID, the caller of the remote execution on Node2 ended up in blocking state forever, waiting on the local blocking queue. To resolve this, the code has been updated to ensure the blocking queue is created and stored in the local queue cache before publishing the remote job message.
