Hi, Greetings for the day,
We are facing a strange problem in Solr cloud where a few requests are taking hours to complete. Some requests return with a 0 status code and some with a 500 status code. The recent request took more than 5 hours to complete with only a 9k results count. These queries create problems in closing old searchers, Some times there are 3-4 searchers where one is a new searcher and the others are just stuck because a few queries are tracking hours. Finally, the application slows down horribly, and the load increases. I have downloaded the stack trace of the affected node and tried to analyze this stack trace online. but I couldn't get many insights from it. . Stack Trace: https://fastthread.io/my-thread-report.jsp?p=c2hhcmVkLzIwMjIvMTIvOC9sb2dzLnR4dC0tMTAtNTUtMzA=&; JVM Settings: We are using Parallel GC, can this be causing this much log pause? -XX:+UseParallelGC -XX:-OmitStackTraceInFastThrow -Xms12g -Xmx12g -Xss256k What more we can check here to find the root cause and prevent this from happening again? Thanks in advance
