Re: [Treebase-devel] treebase problem this afternoon

Hi Bill.

No changes to any settings except increasing the max heap size on tomcat on
production from 3 GB to 4 GB.  No updates to Tomcat, but regular updates to
Apache and the Linux OS do occur on an ongoing basis.

The only change in response to the large number of API hits was to limit
the number of requests per second.  I just disabled that setting on both
systems.  Please try another upload.
