This related to enhancement #705 which times out commands if they run for more that 10 minutes.

Obviously, your hg log command takes too long to finish. I'd advise to tune it like this:

put this into /etc/opengrok/readonly_configuration.xml

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.6.0_06" class="java.beans.XMLDecoder">
 <object class="org.opensolaris.opengrok.configuration.Configuration">
  <void property="CommandTimeout">
   <int>7200</int>
  </void>
 </object>
</java>

and execute the indexer like this: READ_XML_CONFIGURATION=/etc/opengrok/readonly_configuration.xml /usr/opengrok/bin/OpenGrok index

The above will give you 2 hours for each executed command (like hg log) which should be sufficient.
