Bugreport: Ping latency problem with graph enabled

dg1 · Sat Sep 15, 2018 9:40 pm

Hello,

After 1 month, i done a lot of tests and i want report a bug.

Reproduce:

Ping from wired PC to Mikrotik IP for some hours and you can see stable ping. After that, enable all graphs from web interface. You will se every 300 pings a small o big delay. If you disable all graphs, you will not have more delays again.

Hardware and software in:

- CCR1009-7G-1C-1S+: 6.44beta6 (small delays without lost connectivity)

Both routers was tested using SFP GPON to connect to internet.

Do you have some information about this problem?

When you login in web interface, i also see delays when you click in different options.

Thanks.
