Ah, that's helpful. So you're on a platform and version which supports CMP. CMP and persistence don't work so well in current versions. And there is a bug whereby CMP isn't automatically disabled on virtual servers which use persistence (with an exception of cookie insert). See these solutions for details:

 

 

SOL7751: Overview of Clustered Multi-Processing (https://support.f5.com/kb/en-us/solutions/public/7000/700/sol7751.html - Click here).

 

 

If a virtual server references any of the following BIG-IP system features, CMP is disabled for that virtual server and handled by TMM0 only:

The best solution might be to disable CMP for the virtual server you want to use UIE persistence with.
