Page request causes screen-scraper to hang

Making a request to load a page fails (see log below). Screen-scraper hangs and after 10 minutes I had to stop it. Sometimes the first (or second) run will work but multiple attempts will eventually cause a problem.

I also have a single extractor pattern

Thanks, Jeremy

ClassNotFoundException

Now the upgrade is causing this error message: ClassNotFoundException (line 100): com.microsoft.sqlserver.jdbc.SQLServerDriver

100 Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
101 conn = DriverManager.getConnection("jdbc:sqlserver://" + url + ":" + port + ";"
+ "instance=" + instance + ";databaseName=" + database + ";" +
"userName=" + user + ";password=" + password + ";");

Nothing was changed, just ran the upgrade...

That is very different. Do

That is very different. Do you have a script to connect to a SQL Server database? If you disable that script (or comment out the connection), do you get that error?

Yes I agree that it's not

Yes I agree that it's not related to the original issue. I ran a couple of tests in a different project and it looks like the issue is gone.

This project has to connect to a sql database to get a list of links so I can't completely test it. Also the update will have to go on a production server so the new error message will prevent an upgrade.

I'm using the sqljdbc4.jar placed in the lib/ext directory.

I can think of no reason that

I can think of no reason that wouldn't work. I use the mssql-jdbc-6.4.0.jre8.jar and it is working. That is the right version for Java 8. Would it be worth trying?

Can you send an example of

Can you send an example of the connection code? I tried the mssql-jdbc-6.4.0.jre8.jar and still receive this message:

The error message was: ClassNotFoundException (line 100): com.microsoft.sqlserver.jdbc.SQLServerDriver--Sourced file: inline evaluation of: ``//////////////////////////////////////////////////////////// /////////////////// . . . '' : Method Invocation Class.forName

I just tested this in v

I just tested this in v 7.0.11a and it worked. Could you update and test? You could also try to change the HTTP client on the session > advanced tab.
