We are using postgres-xl 10 alpha2 and postgres-xl 9.5 in 2 different clusters but in both happens the same: 
We have found out that GTM fails without leaving any message although we have seen in Ganglia the node where GTM is installed (VM) reached a peak in memory. We have increased the node memory to 64GB from 32GB but it is still happening. Nothing was running at that time in postgres-XL. 
We have setup a GTM slave but the promote it is not automatic. How can we understand what is happening to the GTM and why?
