Get Error: [object XMLHttpRequest] on my PC browser
- 
 *** This issue is not caused by pfsense upgrade to 2.3.3. It is something to do with my PC but I am hoping someone can help me figure it out. Please read for more details *** After I upgraded to 2.3.3, I get this error "Error: [object XMLHttpRequest]" on the Traffic Graphs widget (on dashboard). It does not happen right away but 100% re-createable if I leave the dashboard page up for a while. I have tried Chrome/FF/IE (win 10 machine) and the I get the same error, at the same time for all 3 browsers running simultaneously. I do not get the error if I go directly to Traffic graphs via Status–>Traffic Graphs However, I do not believe this is a pfsense error. I have tried on another 2x win 10 machine and a windows 7 machine and I do not get the error for the same pfsense box. Does anyone know how to fix this or if i can remove/re-install something in the background. Thanks in advance

 I am seeing this as well in the traffic graphs. Restarting PHP-FPM fixes it for awhile. Out of the 4 firewalls I manage, 2 are i386 builds and are the only ones experiencing this. 2.3.3-RELEASE (i386)

 I remember noticing that pfSense has done this ever since the 2.2.x->2.3.x update on i386 builds as well. It used to give certificate error messages but now it just breaks :) I've tested with windows 7 with IE11. EDIT: Just got the certificate error, and now the traffic graph doesn't display with the error message.

 Its annoying and i also noticed after going to 2.3.3 last month. I tried the restart PHP-FPM from console and still get the error. Please post if you find a fix.

 Just to bump this, I noticed that every nanobsd upgrade on pfSense has been plagued with the "/etc/rc.conf_mount_rw" issue. I thought nanobsd was always set to read-write, but I cant upgrade without setting /etc/rc.conf_mount_rw from the shell.
