* this env is just a test cluster: I want to verify the max collection
number solr can support stably.

“no registered leader” is the effect of some problem usually, not the root
cause. In this case, for instance, you could be running out of file handles and
see other errors like “too many open files”. That’s just one example.
One common problem is that Solr needs a lot of file handles and the sy
What is the reason for this number of replicas? Solr should work fine, but
maybe it is worth to consolidate some collections to avoid also administrative
overhead.

To solve this issue, I have read the performance guide:

You say “..it’s unstalble…”. _How_ is it unstable? What symptoms are you seeing?
You might want to review:

Hi,
we are usually using Solr Clouds with 5 nodes and up to 2000 collections
and a replication factor of 2. So we have close to 1000 cores per node.
That is on Solr 7.6 but I believe 7.3 worked as well. We tuned a few
caches down to a minimum as otherwise the memory usage goes up a lot.
The Solr
