Robert Muir commented on SOLR-5277:
-----------------------------------
I searched with eclipse for "commitScheduler" and found it here.
So here is an untested example of what i mean:

> It is handy that certain Java classes stamp a [coreName] on a log entry. It
> would be useful for multicore setup if more classes would stamp this
> information.
> In particular we came accross a situaion with commits coming in a quick
> succession to the same multicore shard and found it to be hard time figuring
> out was it the same core or different cores.
> The classes in question with log sample output:
> o.a.s.c.SolrCore
