This is the second time this has occurred since using v18 EAP. I've also had this issue occur a couple times when running v17 but it wasn't as frequent. With v18 EAP, after Sophos XG has been running for several days (over a week), sometimes the internet becomes unresponsive as in I can't access anything. For example, if I try to access a website, it just continues trying to load and eventually times out. At first, I thought it was an ISP issue so I would reset my cable modem but that didn't fix the issue. I can still access devices on my local network just fine, such as the Sophos XG web UI. What I did notice in the web UI is the "Sessions" count under System in the Control Center indicates a very high number when I'm having these issues. It seems to fluctuate from ~800 up to 2.5k. I have about 30-40 devices on my network (one computer, mobile devices, smart home devices, etc.). Typically, my Sessions count is somewhere around 20-50. After restarting Sophos XG, the count goes back down to what I normally see and everything works fine.
Anyone else experiencing similar issues? Is there any specific log I can save when this issue occurs? Unfortunately, I'm running this on my home network so I can't just leave it in an unusable state.
