We are running Self-Optimizing Block v2.0.2.75 in a loadbalanced environment with three webservers. In front of these webservers there is a apache-server. 

We see that the counters for Exposures and Conversions are counting both up and down. The counter for Conversions is being reset after awhile, while Exposures-counter mostly counts upwards.

Are there others who have experienced similar? Any ideas on how to solve this?
