We're running IIS 6.0 on Windows Server 2003. The server is set up as UK English, which may have a bearing. Occasionally after an app pool recycle we'll see the corresponding ASP.NET 2.0 website start to throw errors with the message
String was not recognized as a valid DateTime.
The only way I know to resolve this is to manually recycle the app pool, at which point all is good again.
Is anyone aware of this problem, and any fix (beyond upgrading etc.)?
