Frame dropout issue while using custom model

My Goal is to implement Custom models

I am executing deepstream-nvdsanalytics program

Hardware: Nvidia Jetson Nano
DeepStream Version: 5.0
Checked Models: SSD, FASTER-RCNN, YOLO.

I have changed the interval value from 0 to 5 in the pgie-config-file, and executed the program with custom SSD model it works well without any framedrops.
With the same interval value trying to execute the custom models of yolo, faster-rcnn i get a frame_dropout issue.

My Question:

How to solve this issue?
