Problem
Network-mounted media disconnects during long exports and causes otherwise valid renders to fail.
Solution
Root Cause / Diagnostic:
Long-form multi-pass exports sustain high read throughput over network-attached storage (NAS/SAN) via SMB or NFS protocols over hours. If the operating system's network interface card (NIC) initiates energy-saving sleep modes, or if TCP keep-alive packets timeout due to momentary network switch congestion, the OS unmounts the network volume. The NLE immediately loses access to the source media file descriptor, terminating the export with an I/O read failure.
Actionable Fix:
1. Disable power-saving modes on the workstation network adapter: in Device Manager, open NIC properties and uncheck 'Allow the computer to turn off this device to save power'.
2. Mount NAS shares using persistent SMB configurations with increased timeout thresholds (e.g., set SMB2 Client SessionTimeout to 300 seconds).
3. If network instability persists, consolidate sequence media to a local high-speed NVMe RAID array before initiating multi-hour batch exports.
Pro Tip:
Utilize dedicated 10GbE or 25GbE fiber network adapters with Jumbo Frames (MTU 9000) enabled on both workstation and storage server to eliminate network packet collisions during heavy concurrent rendering.
