Facing issue when posting a large amount of data to ThingsBoard using Paho MQTT

Question

I've recently encountered an issue while trying to post a substantial amount of data to ThingsBoard using the Paho MQTT client. The error message

Failed to process session update. Max session updates limit reached.

Has anyone else encountered this issue with the "Failed to process session update. Max session updates limit reached" error when using Paho MQTT to post a large amount of data to ThingsBoard? If so, what steps did you take to resolve it?

I also tried to change thingsboard fallowing settings in /etc/thingsboard/conf/thingsboard.conf:

export NETTY_MAX_PAYLOAD_SIZE=1095536000
export TB_SERVER_WS_DEFAULT_QUEUE_MESSAGES_PER_SESSION=1000000
export ACTORS_MAX_CONCURRENT_SESSION_PER_DEVICE=1000000
export MQTT_MSG_QUEUE_SIZE_PER_DEVICE_LIMIT=1000
export TB_QUEUE_PUBSUB_MAX_MESSAGES=10000
export TB_SERVER_WS_DYNAMIC_PAGE_LINK_REFRESH_POOL_SIZE=1000

Apparently, there is a rate limit defined in WS_UPDATES_PER_SESSION. WS_UPDATES_PER_SESSION is set here and it seems to be set from the tenant configuration.

"WS updates per session" should be configurable on the tenant profile details:
