Running Pydio Cells in docker on linux. Out of the blue Pydio Cells became dog slow. Checking logs was presented with a recurring error of: nats - Slow Consumer Detected: WriteDeadline of 2s Exceeded… Restarting the container cleared up the issue. Any suggestions on how to chase down the root cau…

Hello, can you give more info about your setup : Pydio Cells version? Hardware sizing (mem/cpu) Possible IO limitations, ulimit value Amount of users, amount of files -c

If that happens again, first think would be to “ps aux” / “top” / “htop” to detect which Cells process is hogging the CPU. Eventually if you are motivated, you can also send a…

@charles Hi Charles, Had a similar issue today however the mysql container was the gross CPU abuser instead of the cells container (500% vs over 100% for cells). MySQL is spun up with its default configuration with the exception of the character_set_server = utf8mb4 and collation_server = utf8mb4_…
