Solr: The operation has timed out.

0

Dear Community,
does anyone experience such error in Solr?

SolrNet.Exceptions.SolrConnectionException: The operation has timed out ---> SolrNet.Exceptions.SolrConnectionException: The operation has timed out ---> System.Net.WebException: The operation has timed out at System.Net.HttpWebRequest.GetResponse() at HttpWebAdapters.Adapters.HttpWebRequestAdapter.GetResponse() at SolrNet.Impl.SolrConnection.GetResponse(IHttpWebRequest request) at SolrNet.Impl.SolrConnection.PostStream(String relativeUrl, String contentType, Stream content, IEnumerable`1 parameters)
[...]
The operation has timed out Atomic update content:

Random elements in WEBCON can't be proceeded by Solr. I have added RAM for Solr (4GB).
Solr Cloud node shows:
1% CPU, 40% Heap, 1.8 Gb of Disk usage, where 1.5 are BPS_Elements, 330MB are BPS_Activites.

Looks like Solr is working fine, but for random elements it gets "hang".

Updated to latest version of WEBCON BPS but without any change. Using 2022.1.4.346. Tried to use OpenJDK 21 (instead of default 16) - same result.

Any feedback is highly appreciated.
