After I updated dmx-platform to 5.1 I got the error below.
An error occurred while starting "DMX Core":

In production the process doesn’t end, just stops at this line
INFO: Initiating Jersey application, version 'Jersey: 1.14 09/09/2012 05:39 PM'
If I run npm run dev in a new window the process finish and opens localhost although is not editable
I looked for the error and found out that using lsof can determine the processes that locked the db
lsof dmx-db/neostore.propertystore.db.index
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 2025 xxx txt REG 1,2 10485 72015843 dmx-db/neostore.propertystore.db.index
java 2025 xxx 106u REG 1,2 10485 72015843 dmx-db/neostore.propertystore.db.index
But from that point I don’t know what else needs to be done, I killed the process in the activity monitor, but then after use mvn pax:run again got the same error.
