Site changes take site down with Proxy Cache Purge plugin enabled

For the last 5+ months, any time a change is made to my site (a new post, modifying a post, a visitor leaving a comment, me moderating a comment), the site will become unresponsive. The longer the site goes without a change being made, the more likely and lengthy that downtime seems to be. I found that deactivating the Proxy Cache Purge plugin avoids the issue, but that means I have to reactivate it, purge the cache, and deactivate it again after I make each significant change to the site.

Since Proxy Cache Purge 5.0 came out, the problem seems somewhat better but is still present. Any change to my site used to take the site down for 2-30 minutes. Now, the site only goes down for 20-60 seconds, but since that happens with every single change, it adds up. (With Proxy Cache Purge disabled, changes go through in 1-2 seconds.)

The problem is still present with all other plugins deactivated and when using the default, updated WordPress theme.

I’ve talked extensively to DreamHost support, but they closed my ticket when we found that keeping Proxy Cache Purge deactivated avoided the problem. If a fix were possible instead of just a workaround, though, that would be great. That DreamHost support message was #190204858 from 03/06/21.

Thank you!
