I am Home license user with a Sophos AP55 connected directly to my UTM hardware running on ASG software v9.312-8. AP has the latest firmware from what I can tell:
I am getting an ominous-looking error usually once a day in my wireless.log that appears to be a buffer overrun. See log snippet below. I can provide full daily logs if it would help.
Has anyone else seen this particular behavior? It seems to crop up, then all is well. I have had this behavior once, though, require me to power cycle the AP.
As a home license user who purchased an AP through a reseller, what is my recourse to investigate this through support?
