Red Hat Bugzilla – Bug 115367
race condition on "read enablement" creation.
Last modified: 2016-05-05 01:02:40 EDT
Description of problem:
Some read enablements end up being duplicated somehow. The result is
that multiple enablements for the same instance are active at the same
time. Pretty much any PL/SQL that looks at enablements is going to
barf then. A typical webalert will report "Too many enablements for
Fairly unusual. Actually only about 3 classes have ever been affected.
Steps to Reproduce:
Not sure yet, but I suspect it involves the instructor double-clicking
the enablement confirmation. Certainly the "default student" has had
this problem in some cases so it's probably not a student interaction.
