Hello,

Just before updating to version 4.7.3 I’ve been getting this error in my logs:

**2017-11-16**  
04:21:42 **comment**  
server Zero sized function (client:1277928218:FMLE/3.0 (compatible; FMSc/1.0)): type:20 size:0: **x-duration:** 172.133

This would show up in the log up to 500+ times per second and would eventually crash Wowza. I did the update with the hopes this function would be resolved but I am still seeing it. I have removed all incoming live connections to the system from a Flash Media Live Encoder source yet this this persists. It continues to plague the system and causes it to crash multiple times per day. Any assistance would be greatly appreciated. Thanks!
