Tools graphing ps/daemon crashes on 7.20.x CCR

After a few weeks of uptime, about 1-3, the graphing daemon crashes.

I’ve tried multiple versions of 7.20.x and this persists on 7.20.8 (long-term). Currently running a CCR2116-12G-4S+

Most of the traffic is on an SFP+ 10G interface.

Previously it was a CCR1036 and I thought it was bad so I replaced it with the 2116.

Both of them would graph for those few weeks and then the images stop generating. Both will hang when doing an export:

/tool/graphing/export

2026-04-23 15:44:44 by RouterOS 7.20.8

software id = fffffffffffff



model = CCR2116-12G-4S+

serial number = fffffffffffffffffff

Requesting the page host:81/graphs just loads for a minute and offers a blank white page (no html at all).

There aren’t a whole lot of config options, I’m wondering if this is limited to a bugfix or if there is something I can do to work around?

I sent this in to Mikrotik Support sup-215398
