rsyslog 8.2002.0-0adiscon3trusty1 file not transmit suddently

[lynnnn12300]

rsyslog version: 8.2002.0-0adiscon3trusty1
we found that some log rotate very fast ,about 2min a log file, the rotate is mv the current file exp: json.log to json.log.1 , and will write a new file named json.log，when json.log comes to 100MB, it will mv json.log to json.log.1 ,and the old json.log.1 to json.log.2 ,as such and go on...

receiver log sees the log has not transmit about 10mins:

client sees the log is rotate, and new file name json.log:

rsyslog client config: just incluede the json.log , is there any problem?
