It may be they updated something or you’re getting too much traffic than your server can handle. If nothing was changed in the software, it shouldn’t be changing like this really as it’s the same exact queries running these.

marklcfc Posted October 12 Author Posted October 12 The longest crash yet and thats with query cache turned off
marklcfc Posted October 12 Author Posted October 12 For comparison the past two weeks this is where the processor usually is
marklcfc Posted October 12 Author Posted October 12 (edited) It's worse now with query cache off and it was already a complete mess Edited October 12 by marklcfc

Mick23 Posted October 13 Posted October 13 FWIW I experienced CPU spikes on my community and it turned out that I had a lot of bot traffic (looking at you, Bing) causing long-running SQL queries that would max out the allowable connections, and everything would grind to a halt. I blocked a bunch of known bots (and AI scrapers) and the issue was resolved.

That's reminded me I had this kind of thing happening 2/3 years ago and worked out it was a specific bot which I blocked onto my robots txt but about a month ago I reverted it back to the default Invision. I've put those bots back on my custom robots.txt now, really hoping that stops this
marklcfc Posted October 13 Author Posted October 13 I've not had a problem for 2 hours since adding those back in 🤞
marklcfc Posted October 13 Author Posted October 13 I thought it was fixed but it’s started to happen again 😔😔

If it's malicious or not obeying your robots.txt, you'll want to block it at the network/server level.
marklcfc Posted October 13 Author Posted October 13 Seems to be alot coming from Tencent but don't know how to block it in robots. I've turned on this in Cloudflare to see if it helps
Jim M Posted October 13 Posted October 13 You’d want to block in CloudFlare or have your hosting provider block them on the server.
marklcfc Posted October 13 Author Posted October 13 I don't completely know how but I've tried blocking by ASN
Jim M Posted October 13 Posted October 13 You would need to contact the corresponding provider for assistance
marklcfc Posted October 13 Author Posted October 13 (edited) I've tried blocking it on cloudflare but its made no difference, just don't know what to do I'm just guessing Edited October 13 by marklcfc
Jim M Posted October 13 Posted October 13 If you don't know how to block them effectively, you would need to contact your hosting provider or CloudFlare to block them.

Randy Calvert Posted October 14 Posted October 14 You said that you have blocked them, but the question is if it's still them accessing the site. Look at your server logs to confirm. It may not be the traffic you're blocking that is problematic for you. If you're seeing IPs that are supposed to be blocked, then obviously there would be a configuration problem.
