Slowed Down Until Re-Install

I’ve recently experienced some strange behavior that might be w3tc related. I have no idea if this is an interaction with something else or just w3tc.

One of my websites kept having intermittent speed issues, with access getting slower and slower over time, finally getting to where page updates could take upwards of a minute when it started misbehaving. This wasn’t consistent, and it wasn’t until I told w3tc to flush the cache and it just never came back that I suspected that w3tc was somehow involved.

Last week I when it got really bad, I removed and reinstalled the plugin and everything has been fine on that site since. Initially it was only one site, and I dismissed it. Now I’ve had the same thing happen on another site and different server. Fixed it the same way, just remove and reinstall the plugin.

I did check that it was not the server, which was running just fine. In both cases only that particular WP install was slow. Other WP installs on the same hosting server using the same sql server were running fine, as well as cpanel and ssh access at the same time the problem website was not responding.

Has anyone else experienced anything like this?
