Minim stream being throttled on QNAP NAS ?

[simoncn]

It sounds like something else running on the NAS is using excessive system resources (CPU, memory, disk I/O, network bandwidth) and this is not leaving enough system resources for MinimServer to run correctly.

To see what system resources are in use, open Resource Monitor on the NAS. The Overview page shows CPU, network and memory usage. The Storage Resource page has a Disk Activity tab that shows disk I/O activity on each disk. The Processes page shows CPU and memory usage for each running process.

Another possibility is a hardware fault. For example, a faulty HDD could be doing excessive retries trying to read bad sectors. This should show up in the Resource Monitor data.
