Karl Wright commented on CONNECTORS-1489:
-----------------------------------------
Hi [~shashank.raj], this is actually a result of your setup, and is not a bug
with ManifoldCF.
You need to be aware of the following things when sizing the agents process:
(1) If you are not using the extracting update handler, the ENTIRE document is
fetched into memory.
(2) This can occur at the same time for every worker thread.
(3) In order to size your JVM properly with your configuration, you must
therefore multiply the number of worker threads by the document maximum size
(as you configure in your Solr connection), and add 100MB for overhead.
Thanks!

> Hello Karl,
> GC Overhead heap error occurs each time and tomcat closes. Heap allocated is
> 7Gb(Xmx). Is there any other reason this issue is coming up? I am using
> ManifoldCF's tika.
> I have Unchecked "Use Update Extract" and max doc size as 50mb.
