After the upgrade to Merlin 384.15, I've had the "Your router is running low on free NVRAM" warning. My first thought was that the three SSH authorized keys I stored in Admin>System>Service were the main problem. I removed them and the warning message went away.

Since I want the SSH keys there if possible, I read through the forum to find other ways to minimize NVRAM usage. I was successfully able to setup DHCP allocations with /jffs/configs/dnsmasq.conf.add instead of the GUI, but it wasn't enough to remove the errors. I then found a "for" loop that removed empty lines in the NVRAM and recommitted it. THAT lowered the NVRAM usage from 62k/65k to 51k and no warning.

I'm coming to the forum now to find out if there's a way to remove the three authorized keys from the GUI configuration and somehow put it in the jffs section, like the DHCP reservations. Any advice on this, or other things I can do to minimize NVRAM usage appreciated.

Thanks! :)
