Hi John Reynolds,
We are really sorry that you are having this problem running the web site indexing.
Considering the information provided so far, we think that the indexing goes smoothly. The problem is that it is interrupted by operation timeout, which can be avoided, fortunately. There are two possibilities for extending the timeout period.
The first one is setting the httpRuntime executionTimeout="99999" to almost unreachable size. It is important to set the <compilation debug="false"> if you chose this option.
The other option is setting <compilation debug="true">, therefore it would not be necessary to add anything more just because it is excluding automatically any kind of timeout defined in the configuration file.
Another thing which may be helpful for reaching the root cause of the issue is the Sitefinity.log file, stored in ~/YourProject/App_Data
. It would be really helpful if you can send it to us for deeper investigation.
Hope that the provided information is helpful.
