I installed the BitNami Redmine stack 2.0.1 on Windows Server 2008. Everything was working fine but after few minutes of browsing the Redmine site, I suddenly get a "503 service temporarily unavailable error".
I have to restart the "thin_redmine2" service manually using the BitNami manager tool in order to solve this but the behavior returns.
Update: In the Redmine production.log I can see the message "Lost connection to MySQL server during query ..." around the time of the error.
Any clue?
