Hi all,
We are using solrcloud 4.4 (solrcloud with external zookeeper, 2 tomcats ,
2 solr- 1 in each tomcat) for indexing delimited files. Our index records
count to 220 Million. We have three different files each with a partial set
of data.

We index the first file completely. Then the second and thrid files are
partial updates.

1. While we are testing the indexing performance, we notice that the solr
hangs frequently after 2 days. It just hangs for about an hour or 2 hours
 and then if we hit the admin url , it comes back and starts indexing. Why
does this happen?

We have noticed that in the last 12 hours , the hangin was so frequent .
almost 6 hours it was just in hanged state.

2. also, commit time also increases for the partial upload.


Do we need to tweek any parameter or is it the behavior with Cloud for huge
volume of data?


Thanks,
Prasi
