Till now it was running with 45GB heap memory. I am trying to tune the

What is the total index size and total doc count of the server?
In the past I have run Solr servers with 80 million documents across 3
cores taking up over 100GB of disk space (can't remember the exact size)
with the max heap set to 8GB.
Unless your index is REALLY huge, I cannot imagine it needing a heap
size of 31GB or more. Do you have any evidence that the heap actually
needs to be that big?
If you provide some GC logs from Solr, they can be analyzed at
https://gceasy.io to determine whether you really need a heap that big.
Note that you should not send them as email attachments because the
mailing list will most likely eat them so we never see them.
Thanks,
