We are using Umbraco 7.1.8 with Url Tracker 3.0.1.

We have an intermittent problem where our site will crash. When we look in the logs, we see a whole lot of errors like this:

2015-07-16 12:32:41,386 [5] ERROR Umbraco.Core.UmbracoApplicationBase - [Thread 49] An unhandled exception occurred

It is unclear if the Url Tracker is the root of the problem or if it is just throwing the most errors when the database is too busy to respond.

I am wondering if anyone has seen this problem or if they know if an upgrade to the latest Url Tracker will help. I saw an improvement for version 3.8 of UrlTracker that says "no SQL queries will be performed anymore for valid requests". I'm hopeful that someone else has experienced our problem and seen versions 3.8+ as solutions. Any thoughts?
