[Plugin: Feedwordpress] FWP randomly generates a 404 when manually updating

Running the latest version of FWP (2011.1019) with the latest versions of the add-ons FWP+: Limit size of posts/FWP+: Read More link/FWP+: Strip HTML Tags from Posts/FWP+ Add Attribution

Since switching my Hostgator VPS from suPHP to FastCGI, I am having a weird problem:

I have about 10 Yahoo Pipes RSS feeds I import. In the dashboard, when I manually update the feeds all at once, in 90% of the cases, FWP throws me on my 404 (page not found) page. Sometimes this happens after 10 seconds, sometimes after more than a minute.

Updating the feeds manually seems to have more success, but still there is a 50% chance updating a single feed manually, will generate a 404.

In all other cases, the feeds update OK.

PHP error_log does not have any errors related to FWP, and I don’t see any errors when I switch debugging mode on.

PHP memory_limit is set to 128M (in debug, I see FWP does not take more than 32M), max_execution_time=60 and FWP timeout for fetching single feeds is 120 secs

Any ideas anyone?
