Hello @all, I've got a problem with Solr (version 7.7.2) since some days.
On March, 4th I got an OOM and the log file just says the following: Running OOM killer script for process 12351 for Solr on port 8983 Killed process 12351 So I started the service again and the service is running fine. But if I try to search something I only get the error that the string I searched for wasn't found. Next, I tried to see the status of the process. That only gives me the following error message: ./solr status Found 1 Solr nodes: Solr process 1519 running on port 8983 ERROR: Failed to get system information from http://localhost:8983/solr due to: org.apache.http.client.ClientProtocolException: Expected JSON response from server but received: <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/> <title>Error 404 Not Found</title> </head> <body><h2>HTTP ERROR 404</h2> <p>Problem accessing /solr/admin/info/system.
