I'm using AX55, but today i see my log flooding. What's wrong? No firewall log, no aiprotection.

Code:
dnsmasq-dhcp[1477]: failed to write /var/lib/misc/dnsmasq.leases: No space left on device (retry in 60s)

Any idea?

Same situation here. I’ve reported it via feedback option on the router but not sure if it would be read by asus. This error seems to be happening when instant guard is being enabled. Funny thing is, that there are plenty of free space on the internal disk and memory have got some free chunks either. I thought there are privilege issues of the file as it doesn’t really have write bits set. Changed it and same issue remains. Also, what is funny, after some time, system log will show that it can not fork processes, however, all seems to work for a while but after some time VPN connection would be dropped. If, free memory/ disk is really an issue, while data guard being activated, it’s really a shame and i did not expect such bad testing of the products by asus. My router is a couple of days old and having such issues from the beginning is big disappointment. It’s not that i really need VPN that much but...
