No Graphs, errors in Syslog

Anyone seen this before,

I have used OpenWRT on Linksys E4200, no issue (other than odd reboots) Trying on WNR3500L, Graphs fail to work , on all tabs

Model Netgear WNR3500L
Architecture Broadcom BCM4716
Firmware Version OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.229.71287-57456a7
Kernel Version 4.14.180

Chosing "Realtime Graphs", page shows, but no graphics on any of the tabs..

In SYSLOG and Kernel Log this shows , while page is open

Tue Aug 18 19:35:42 2020 kern.warn kernel: [40863.914486] __do_page_fault: 2 callbacks suppressed
Tue Aug 18 19:35:42 2020 kernel: [40863.914504] do_page_fault(): sending SIGSEGV to luci-bwc for invalid write access to 00000000

Havent found any other examples of this , so raising issue

Updated all software , just in case fixed. Still happeneing

No workarounds found..

@mikerog25, welcome to the community!

Not sure what this mean. Did you flash a new snapshot firmware?

Performing general upgrades on packages (especially ones built-in the firmware) is not usually advised. This may be your issue.

HI, Thanks for reply

It was the same before and after updates anyways.
I noticed there were packages that were updateable, (which was weird as Id' only installed last week from a "CHK" file. for the Router. )

I thought i would do the updates just incase my issue would be fixed in them.. but no luck

Origianaly flashed the Installation from here
Firmware OpenWrt Install URL

Anyone else running a wnr3500l_v1 with 19.07.03 as a 1st install?

Reflash, or downgrade to 18.06.07 perhaps? Any thoughts?

DIsconnected router from Internet, and was ready to downgrade to 18.06, but noticed the graphs started to work, intially for system load, and then the rest of them

Will reconnect to internet soon to see it miraculously fixed , or just fails when connected
