RT–AC66u Network Share Ram Issue

[Mark112887]

Good afternoon,

I've had my router since January 2015 and I've been mostly satisfied with the exception of one issue. I noticed that I would have random reboots of my router, I have been able to track down the cause of this problem until last night. I have been noticing for a long period of time that my RAM usage is always very high, I have all of the extra features in the router turned off with the exception of samba share. It seems that whenever I am accessing any files from a USB device connected to the router my RAM usage will slowly rise starting in about 32% going as high as 72 or 73% at which point the router will randomly reboot and the memory usage will remain in the 70% bracket. The only thing that will return the memory usage to normal is either resetting the NV RAM or as I discovered last night unplugging my USB hard drive.

Is this normal behavior or do I have something wrong with the router?

I have contacted ASUS about this and they want me to send them the router so that they can evaluate it. Problem is I can't do that because I do not have a backup router to use in the meantime. If this is a hardware issue I'll just try my hand at the 3200

Any help or advice on this issue would be extremely appreciated, I'm losing my mind here. Thanks very much

High RAM usage when using a shared USB disk is normal. The router's file server (Samba) will cache the files in RAM as it reads and send them. That memory gets freed whenever another process needs it for more important uses than buffering/cacheing.

The problem is that it goes up and stays up and never goes back down. I've been having this problem basically since I bought the router having to do with random reboots, even on the latest firmware which is 9135 I believe. If I set up the router completely from scratch after clearing the NV RAM I'm able to get it to go for about 15 to 17 days but then it will randomly reboot and after the first time it will continue to reboot randomly in much closer time periods than the initial 17 days. I just don't know what to do, the router should not be overheating it is in a well ventilated area and the only feature I use on the router other than MAC address filtering is the samba share.

Can anybody provide me any information about this? If not I'm really at the end of my rope I may end up trying the AC 3200 to see if I experience the same issue
