Currently I have 6 active devices.
This morning after waking up I looked at my queues, all was rather normal (at 08:54 UTC), especially these two Linux machines:
D2 opng:48 scc1:64
D9 opng:31 scc1:61
(machines D2 and D9 have 48+31 OPNG-tasks and 64+61 SCC1-tasks.)

20 minutes later, still quite normal:
D2 opng:48 scc1:59
D9 opng:26 scc1:57

However, one and a half hour later (at 10:24 UTC), device D9 was suddenly out of SCC1-work (and D2 almost), while OPNG-tasks are still being received normally:
D2 opng:39 scc1:13
D9 opng:47

This would be normal if you suddenly cut the supply of SCC1, but I didn't touch any device profile.
So I decided to edit the device profiles, set MCM1 to 16 and set SCC1 to Unlimited. Soon enough, at 11:00 UTC, all devices were receiving SCC1-tasks again, except device D9:
D2 mcm1:16 opng:49 scc1:109
D9 opng:39

So. after 3 more hours of SCC1-drought on device D9, I decided to edit the 'work' profile to fit the D9 device and assign D9 to that profile.
One hour later I returned and still nothing had happened with SCC1, nor MCM1.

I wonder if anyone else is experiencing something similar.

If anyone of the techs is reading this and able to have a look, the relevant device-ID is 8403220 (and I know it's Friday 17:00 UTC).
