[grondo]

While reloading fluxion on elcap, several pending jobs were canceled with a fatal job exception such as:

[Jun04 14:42] exception type="alloc" severity=0 note="alloc denied due to type=\"match error\"" userid=765
[  +0.000608] clean

For reference, here's the logs at the time of module reload:

Note that in this particular case, we had to kill off flux module remove sched-fluxion-qmanager which was hanging due to the leaked alloc requests issue (can't find the issue right now, feel free to link it here if found)
