Fixed Issues

• Controller takeover would occasionally occur on the ES2486dc for no apparent reason.
• Under certain conditions the GUI performance would become slow.
• Disabling CIFS would sometimes cause the system to be unable to obtain information on storage pools or LUNs, or perform any actions on them.
• Disk SMART information on some NVMe SSDs were incorrectly displayed.
• Under certain conditions, copying data between two LUNs would cause the system to stop responding.
• On a dual-controller NAS, firmware update from a peer controller would fail if the firmware versions between the two controllers did not match after manual update of one of the controllers.
