The web UI page for dn-vnStat doesn't load anymore.
Not only does it not load but it causes httpd to hit 100% CPU use and block the entire router web UI.
Router model AC86U on Merlin 386.7.

This problem appeared right after I upgraded Diversion from 4.2. to 4.3. I don't see the connection between the 2 (maybe there isn't any) but one happened right after the other.

Check the files in /www/ext/dn-vnstat/. Anything really large or old looking? Never used this, but I would start by assuming these data files are part of the problem.
 
This will be a challenge to diagnose.

So if I reboot the router and go to the vnStat web UI page (Addons -> dn-vnstat), the page loads.
If I then go and open a Diversion page (LAN -> Diversion) and then come back to the dn-vnstat page, the whole router web UI freezes. I can't say how consistent this is - already had to reboot 3 times via PuTTY because the web UI stopped responding.

vnStat works by generating usage images every 5 min. Something seems to interfere with the images creation, because they have occasionally started to come out incomplete.

This problem persists, although less severe (or I got used to it and avoid clicking too much around the web UI).
Data appears to be fine but every now and then the page would freeze or images load partially.
Let's say - around half the time. I.e., images are broken, after 5 min they are ok, next refresh - broken again. By "broken" I mean incomplete, like on the attachment above.

I'm definitely not a pro at this stuff when it comes to entware and such, but it just seems to me based on your log that the vnstat2 package/download is either not available or corrupt? That has a cascading effect as the install process unfolds, because files, configs, directories are just not there.

Perhaps someone can chime in to help determine what's happening with that vnstat2 package?

That may be a problem as well:
  • AsusWRT Merlin version 384.19 or later for R1.
    • R1 has been tested on 384.19 through 386.2_6 release version.
      • Earlier versions (384-series only) may likewise function; kindly report any further experiences (include router model and firmware version).
      • Initial testing on John's fork appears to demonstrate expected functionality. Kindly report any further experiences (include router model and firmware version).
    • AsusWRT Merlin version 386.2 or later for R2.
      • R2 has been tested on 386.2_6 release version.
      • No version of 384.x nor John's fork have been tested (no supported hardware available) - please report success/failure.
 
How will I know what is the name of wan in ax58 to set proper name for vnStat ? It assign eth4 by default but isn't it the standard lan port for a connected device?

Usually it's eth0

'no interface matching eth0 found in database'
Click to expand...
So interestingly enough, I was reading up that AX58's use eth4 for their wan0 interface... you can check for yourself running this command and seeing what it comes back with?

Code: 
nvram get wan0_ifname
