Thanks, I'm like that tend to jump into the pool before there is water in it.
I did submit a support ticket waiting for a response.
Please raise a support ticket with Nintex support. Please also quote the Product and Release version number you are using (it looks like you are on-premises from the description in your SQL issue) e.g. NW2013 Release 22.214.171.124. This looks like it is intermittent and so you probably do not have replication steps and this also implies it may be an interaction within your environment. This will be the best way of resolving your issue.

For us the following steps solved the Problem:
I'm also facing this issue. Could you please update if you have received any solution from Nintex team?
We are in urgent need to solve this.
We have the same issue with a customer. Version is on-premise Nintex 2013 (126.96.36.199). Any solutions for this?
Maybe this helps. I tried now to deactivate the Incoming Mail Service on my App Server which doesn't serve users anyway and Web Server role is just running for search. I hope this prevents that incoming mails get to the wrong direction as described here:
