I am currently trying to deploy 126.96.36.199 release of OpenMRS platform on Ubuntu & I am experiencing errors. Some go away after restarting tomcat server. It seems to me that the version 2.x is not currently battle tested. Can you please suggest an LTS version of OpenMRS that is best for long term deployment and can be upgraded to the next LTS version? Please also suggest the recommended versions of the softwares like MySQL, Tomcat etc.
