If I had a pound for every time someone told me that the request didn't make it to the server because it wasn't logged, I'd be a rich man.

 

Logs when present will tell you what happened. When not present, it tells you nothing except it didn't work properly. Absence of logs does not imply that the request didn't make it. (Doesn't mean it did either, but you can't prove a negative generally).

 

You do however need to poke around more... Maybe it's a client that isn't sending the whole request so BigIP is waiting (buffering) until it gets everything.
