Hi, folks!  
Checking the openvidu report, i can see a lot of messages of warning in the log:

> 2023-11-25T13:59:56,206384 1 0x00007f88c3237700 warning kmsutils kmsutils.c:1456 kms\_utils\_depayloader\_adjust\_pts\_out() Fix PTS not strictly increasing, last: 0:45:51.591139556, current: 0:45:46.302236556, fixed = last + 1: 0:45:51.592139556

And when this happens, my cpu goes to 100% and the server network goes to high values. I need close one of sessions to stabilize the server.

I don’t know what is causing this. If anyone can contextualize whether these messages could be an indication of this high CPU consumption, I would appreciate the response in advance!

> Server configs:  
> AMD Ryzen 9 3900 12-Core Processor  
> 62GB RAM  
> OV 2.29

This happens with much more frequency if i leave OPENVIDU\_STREAMS\_VIDEO\_MAX\_RECV\_BANDWIDTH with 0 now i keep the default value: 1000.  
Sent to server: 1000 max - 700 min  
Sent to client: 900 max - 700min

> Scenario:  
> 1 - N  
> Subscribers: 600~800  
> Sessions: 4~6

Thks!
