Hello,
We experienced a problem when creating a core via a request on Solr 9.2.1. It
seems that the core creation for “blueprint_helios_comments“ just “hangs”.
Consequently, with subsequent external requests to create the same core (since
it does not seem to be there yet), Solr detects that the core creation is
already in progress and returns an error.
This is what Solr’s log tells me:
[ blueprint_helios_comments] o.a.s.s.HttpSolrCall [admin] webapp=null

params={core=blueprint_helios_comments&action=STATUS&indexInfo=false&wt=javabin&version=2}

The creation stops after “Soft AutoCommit”. During the same run of Solr and our
test suite, other cores are created successfully.
With the next run of the same software on empty directories and attempt to
create the core, everything succeeds:

I can’t recall having seen this issue before nor can I reproduce it, but I’d
like to ask whether this behaviour is known (couldn’t find a Jira issue or mail
thread connected to this) or anybody has an idea what might be going wrong.
Thanks!
