We switched to webwork 2.12-r on our Ubuntu 16.04 server, and updated the problem library from github. Now when we run OPL-update it seems to finish everything but exits with a warning. Here are the last few lines of its output, including the warning:
"Updating Library Statistics.
Importing statistics for 33 courses.
1 2 3 4 5 6 7 8 9 10
11 12Issuing rollback() due to DESTROY without explicit disconnect() of DBD::mysql::db handle webwork at /opt/webwork/webwork2/bin/OPL-update line 970.
Should we do something about this? What?
Thanks for any suggestions,
