Session violinist disappears after showing

Question

I am tracking an iOS application through a violinist as a proxy. And for some iOS application requests, the violinist will display these sessions in no time, and then these sessions will disappear. This is contrary to my common sense why a mundane session in the violinist will someday disappear. The only thing I can think of is that the response of the http session violates the protocol? But the IOS app behaves normally with these HTTP requests and responses.

I took some screenshots for the HTTP request while it is displayed in the fiddle, and here is what it looks like for each fiddler column:

#:76 Result:- Protocol:HTTP Host:184.102.xxx.xx URL:/someUrl/someHashCode Body:-1 Caching: 

Does anyone know what is going on here?
