Router Model / Version: Dlink DIR-882 A1
File: dlink-dir882-a1-webflash.bin
Firmware: DD-WRT v3.0-r46442 std (04/23/21)
Previous: DD-WRT v3.0-r46395 std (04/19/21)
Mode: AP
Uptime: ~ few hours
Status: working
Services: Openvpn client, DLNA, SAMBA, PPPOE
Issues / Errors: Even if it took more time, with more files being transferred, i finally had the same issue of high CPU usage and NAS stop responding during access to audio files on NAS (hundreds of files). CPU usage start increasing untill it reaches 100%, even if i stop using NAS well before (load keep increasing)

(SMB 3.02, EXT4 Hard drive, No encryption)

I'll try to set the new setting "Connection Limit" to 8 and see what happens (it was on 16 by default)

EDIT: Same issue with "Connection Limit" set to 8, this doesn't seem to be the root cause of the issue
