Error solr

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-user@lucene.apache.org


[cid:image001.png@01D7C5CA.A2F09360]










This is my solr installation:
[cid:image002.png@01D7C5CA.A2F09360]

Can you help me to understand this kind of error and the possible resolution?

Thanks,
Pasquale

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?

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.
