[Andreas Dilger]

It may be that increasing the timeout for jobid expiry by a second or two would be enough. The most efficient way might be to use wait_update() with a maximum of (left + 5) seconds so that it doesn't wait longer than needed.

[Andreas Dilger]

Bob, assigning this to you for further investigation. It seems to be failing regularly for SLES11 SP3/SP4 tests, and even if we could get those patches to pass once, this is failing for more test runs than it is passing and we would just be introducing a regression by landing those patches.

[Andreas Dilger]

It looks like this test is only failing on SLES11 SP3/SP4 and not others.

It's easily reproducible on master
