I have been running a bunch of temporal queries. My timeout is set to 60 seconds (and other queries run over 60 seconds), but these queries are "canceling" at about 30 seconds. When they do, they are immediately available in Previous queries as "Finished". Is the completion process for these queries being inadvertently interpreted as a timeout?

If the query completes in a very short time, it works as expected. Easy to reproduce but not totally consistent since there is not ostensible difference between a 15 second and a 30 second query - right?

Could it be your Apache timeout?

1. The default timeout is 60, this needs to be increased for long running queries.

2. in the /etc/httpd/conf/httpd.conf file add "TimeOut 240" into the VirtualHost directive.
