SharePoint 2013 event receiver error

Question

I am currently working on a SharePoint online project. I am facing a strange issue. My code generates 6 documents
in 6 different document libraries along with other metadata. When I save data to a List, the event receiver fires and creates all the 6 documents. But sometimes it stops creating the 6 documents and left with 1 or 2 documents. Sometimes documents has been
created but without any metadata. The same code is working fine in my on-premises environment, but it sometimes breaks in the Office 365 environment. I also created a log list to track the issue as we cannot debug in Office 365. In the log list I found a error
message saying "Thread was being aborted." Below is my code. please help it is happening only in Office 365 environment.
