We will attempt to reproduce and resolve the primary issue, and produce a more informative message in the second case.

Dave, can you provide a sample job that demonstrates this (sporadic) failure? I need to know:
mu2egpvm01
)mu2e
Offline you're using if the job depends on anything from thereart
--the "Occurs In" field says you observe this is cetlib:version:1.03.09, which does not correspond to a version of art

I have not been able to reproduce this error. I suggest we close this issue for now.

Thank you, Dave, for the extra information. I will put the issue in "Remission" state to reflect that it may still be an issue later on.

I am using the dbOutput (SQLite) output of TimeTracker to study module timing distributions. This works when I create a new file for each run. If instead I use the 'overwrite' option (overwrite : true) to overwrite an existing file, art sometimes issues an exception, noted below. The exception seems to be issued randomly (rerunning the same job multiple times produces different results), but is fairly consistently produced when processing more events the 2nd time than the first.
As a more minor but annoying issue, I note that, without the overwrite option, if I try to write to the same database file, the exception message is obscure and doesn't help the user understand what the problem is.
