Pasquale, Are you using any custom written components anywhere in your solrconfig? It's possible that in your custom code you are calling getCore() on a SolrQueryRequest object and then calling a close() on that core. Since getCore() doesn't increment the ref count of the core AND core.close() decrements it, this could be a possible cause of your issue. (This is tricky since a getCore() on a core container object DOES increment the ref count and so you need to call core.close() when done with the core from CoreContainer object)
Also, do you see a "SolrCoreState already closed" exception anywhere in the logs? -Rahul On Wed, Oct 20, 2021 at 11:15 AM Atita Arora <atitaar...@gmail.com> wrote: > Hi, > > I once had this issue too , not sure , are you also writing intensively ? > Looking at the code too , it looks like it's just trying to close the > writer stream and related resources > searcher / updatehandler . > Although I do see https://issues.apache.org/jira/browse/SOLR-4753 as well > open. > As the code says (from where the error message originated) on close : > > If reference count is > 0, the usage count is decreased by 1 and no > resources are released. > If reference count is == 0, the resources are released. > If reference count is < 0, and error is logged and no further action > * is taken. > > HTH. > > > On Wed, Oct 20, 2021 at 3:55 PM Pasquale Moramarco <p.morama...@reply.it> > wrote: > >> Hi, >> >> >> >> I’m using solr and I have this issue: >> >> >> >> 20/10/2021, 15:29:44 >> >> ERROR true >> >> x:product-hash_shard1_replica_n1 >> >> SolrCore >> >> Too many close [count:-22] on org.apache.solr.core.SolrCore@6d0f1fd4. >> Please report this exception to solr-u...@lucene.apache.org >> >> >> >> >> >> >> >> >> >> >> >> >> >> This is my solr installation: >> >> >> >> Can you help me to understand this kind of error and the possible >> resolution? >> >> >> >> Thanks, >> >> Pasquale >> >> >> Pasquale Moramarco >> >> Blue Reply >> Via Giuseppe Sangiorgi, 15 >> 70124 - Bari - ITALY >> phone: +39 080 9727039 >> p.morama...@reply.it >> www.reply.it >> >> [image: Blue Reply] >> >
