After I installed the base (1.4 community) - I felt it necessary to fill
existing data (users of the system and relations between them). Total users
about 1.6 million and 4.5 million links.
I wrote a robot, using REST-requests and creates the necessary link between
the top two.
After I ran it and measured the rate of filling databases - according to my
calculations, the robot had to work 2-3 days. That suits me and I left it
running.
But after about 4 hours, when the copy already around 200 000 relations -
error occurred and the database is not working.
Here's from the log:
