I'm seeing some huge spikes lately on my wiki's server. CPU, the number of entry processes, are all going up. Sometimes I cannot access the page and get something like this instead

At the moment, I don't know if SMT is causing the internal error, or aggravating it, or whether there is high bot activity that negatively affects how SMT performs. I'll disable SMT and see if that helps.
- SMT 4.1.1
- SMW 6.0.0
- MW 1.43.5
