Hi I am running solr cloud 4.3.1 (there is a plan to upgrade to later versions but that would take a few months). I noticed a very peculiar solr behavior in solr that beyond *2496* cores I am unable to create any more collections due to this error
*Could not get shard id for core.....* I also noticed in the solr "tree" view that the overseer's collections work queue gets stuck ( /overseer collection-queue-work qn-0000000360 qn-0000000362 qn-0000000364) The test results are as follows. With 8 shards and 2 replicas, I can create 156 collections (and then hit the above error) With 4 shards and 2 replicas, I can create 312 collections (and then hit the above error) With 2 shards and 2 replicas, I can create 624 collections (and then hit the above error) The total no of cores is 2496 in all the above cases. I am unable to create any more collections after this due to cannot get shard id error? Is this a known bug or is there a work around for this? Is it fixed in future releases? Thanks much -Nitin
