+
+ Set dropzone parallelUploads to 1 to avoid losing attachments
+
+ RT uses the database to manage sessions and some Apache::Session
+ database modules don't implement row-level locking. For those
+ databases, sending multiple requests at once can cause two processes
+ to both write to the session at once. In these cases the last one in
+ can overwrite and lose changes from other processes. The symptom with
+ dropzone attachment uploads is a missing attachment.
+
+ Set parallelUploads to 1 to only send one at a time to avoid this.
