Nawab What do you see in the log file? If nothing else is solving the problem, then get a sample V7 solrcinfig.xml and use it, modified to suit your needs. Cheers -- Rick On November 22, 2017 11:38:13 AM EST, Nawab Zada Asad Iqbal wrote: >Rick > >Your suspicion is correct. I

Re: Solr7: Very High number of threads on aggregator node

Rick Your suspicion is correct. I mostly reused my config from solr4 except where it was deprecated or obsoleted and I switched to the newer configs: Having said that I couldn't find any new query related settings which can impact us, since most of our queries dont use fancy new features. I

Re: Solr7: Very High number of threads on aggregator node

Nawab Why it would be good to share the solrconfigs: I had a suspicion that you might be using the same solrconfig for version 7 and 4.5. That is unlikely to work well. But I could be way off base. Rick -- Sorry for being brief. Alternate email is rickleir at yahoo dot com

Re: Solr7: Very High number of threads on aggregator node

@rick I see many indexing config, but i don't see any config related to query (i.e., number of threads etc.) in solrconfig. What will be the relevant part for this area? In jetty threadpool is set to 1. @Toke: I have a webserver which uses solr for querying, this i guess is pretty typical.

Re: Solr7: Very High number of threads on aggregator node

Nawab You probably need to share the relevant config to get an answer to this. Cheers -- Rick On November 17, 2017 2:19:03 PM EST, Nawab Zada Asad Iqbal wrote: >Hi, > >I have a sharded solr7 cluster and I am using an aggregator node (which >has >no data/index of its own) to

Solr7: Very High number of threads on aggregator node

Hi, I have a sharded solr7 cluster and I am using an aggregator node (which has no data/index of its own) to distribute queries and aggregate results from the shards. I am puzzled that when I use solr7 on the aggregator node, then number of threads shoots up to 32000 on that host and then the
