MongoDB write error when I m not writing anything to Mongo
-
When I try to render a large report, multiple pdf page ~700 pages, sometime I get this exception, not sure why. This exception usually occurs when trying to write a document larger than 16MB into MongoDB. In my case, I m not writing anything from MongoDB. I use MongoDB to read my data for the template as well as storing and fetching templates. I also changed my blobStorage to use GridFS. Here is the exception. Kindly help ASAP. Thanks!

after having a skype conversation with the user, the problem was that the
settingscollection was constantly growing until the limit of 16MB was reached.i have provided a temporary workaround (commenting the code in jsreport-studio that saves request logs in settings collection) until we solve the problem.
version of jsreport with the issue: 1.4.0
