MySQL or FastCGI problem after upgrading 8.0 -> 8.01 help!

[scarydog]

Kia ora all,

Today I updated from Plesk 8.0 to Plesk 8.01. Everything appeared to work well.

Unfortunately...

Now when a user connects to my Ruby on Rails app they initially get an
Application Error. If they try again (or refresh) it is fine and continues to be fine
until they pause for too long (approx 2 mins). In the logs I am getting
the following error:

ActiveRecord::StatementInvalid (Mysql::Error: MySQL server has gone
away: SELECT * FROM titles )

I have updated the app to Rails 1.1.4 from 1.0.0 but the problem
persists.

Has anyone come across this? Was MySQL upgraded? I didn't see it in the log (which seems to have dissapeared)

I am using MySQL version 3.23.58, Apache and FastCGI. I have tried
setting the timeout on FastCGI to 900 and min-servers to 2 but it still
happens.

Any help would be greatly appreciated!

Regards
Nathan
