[Bigdata-developers] Blazegraph Engine hangs in embedded mode after moving Tomcat
|
From: Joakim S. <joa...@bl...> - 2015-11-18 15:41:17

I have been running Blazegraph 1.5.2 in embedded mode (apache-tomcat-8.0.27) for a few months ( Ill upgrade to 1.5.3 when available on Maven).
After moving Tomcat to another volume with a minor update (apache-tomcat-8.0.27) I can no longer run my service.
The servlet initializes twice. The first time Blazegraph engine starts, but it seems that at the end of its loading process, it fires an new init() to the servlet
