423023 - "MacOSX Darwin 8.8.1 talos trunk qm-pmac01" stopped cycling

Status: RESOLVED INVALID

(Release Engineering :: General, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

qm-pmac01 (on Firefox tinderbox, "MacOSX Darwin 8.8.1 talos trunk qm-pmac01") hasn't cycled since it finished testing the 10:50 build (which completed around 11:17) at 12:25.  The other mac talos machines have been cycling fine during that time, and the Mac nightly box is generating builds.

I'm not sure if this is expected or not, but it seems unusual if not a sign of something broken.  That said, this box does have some gaps in its history earlier today, so this might be normal.  (But if it is normal, why is it normal?)

There are three machines in this group, with only two machines worth of work. So most likely this is just bug 419071.

Looks like this isn't something IT can fix.  Over to Build & Release.

I believe nothing to do here; this is expected behaviour when not enough work to hand out to the 3 slaves for a long period. 

To reduce likehood of long idle times causing concern looking at tinderbox, bug#419071 randomizes which slave is allocated work, but the underlying issue is the same; when there is not enough work for the slaves, *some* slave will be idle until more work appears.
