we have a docker setup for the app and on each container start we try to create all indexes again, just in case, cause we would not know if it is first started or not, etc. But it does not matter.
Point is, sometimes indexing are stuck with:
“Index Build: draining writes received during build”
And they never stop.
It seems to happen with 4.4.4 and now after upgrading to 4.4.9 it also still seems to happen.
And it seems to happen only on Replica sets.
And it happens on collections with low write rates or even empty collections that have no writes.
Could it be related to the bugs fixed in 4.4.9? And we simply need to fix/clean all data?
Or this is something else?
