OMV Keeps Locking Up Randomly

Hi

I have ROCK64 single-board PC made by Pine64. My system information is as follows:-

System Information

Version 4.1.23-1 (Arrakis)
Processor ARMv8 Processor rev 4 (v8l)
Kernel Linux 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310
Load average 0.01, 0.11, 0.14

Running services

SMB/CIFS

SSH

I get really good transfer speeds of 96MB/s so nothing is slow. I notice a lock-up when I'm transferring files via SMB and the progress bar will stop halfway through and trying to access the Web-GUI is unavailable too, but it is completely random when this occurs.

Any ideas?

Many thanks in advance
