Hi I'm working with a Solr cluster with master-slave architecture.
Master and slave config: ram: 120GB cores: 16 At any point there are between 10-20 slaves in the cluster, each serving ~2k requests per minute. Each slave houses two collections of approx 10G (~2.5mil docs) and 2G(10mil docs) when optimized. I am working with Solr 6.2.1 Solr configuration: -XX:+CMSParallelRemarkEnabled -XX:+CMSScavengeBeforeRemark -XX:+ParallelRefProcEnabled -XX:+PrintGCApplicationStoppedTime -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution -XX:+UseCMSInitiatingOccupancyOnly -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:-OmitStackTraceInFastThrow -XX:CMSInitiatingOccupancyFraction=50 -XX:CMSMaxAbortablePrecleanTime=6000 -XX:ConcGCThreads=4 -XX:MaxTenuringThreshold=8 -XX:ParallelGCThreads=4 -XX:PretenureSizeThreshold=64m -XX:SurvivorRatio=15 -XX:TargetSurvivorRatio=90 -Xmn10G -Xms80G -Xmx80G Some of these configurations have been reached by multiple trial and errors over time, including the huge heap size. This cluster usually runs without any error. In the usual scenario, old gen gc is triggered according to the configuration at 50% old gen occupancy, and the collector clears out the memory over the next minute or so. This happens every 10-15 minutes. However, I have noticed that sometimes the GC pattern of the slaves completely changes and old gen gc is not able to clear the memory. After observing the gc logs closely for multiple old gen gc collections, I noticed that the old gen gc is triggered at 50% occupancy, but if there is a GC Allocation Failure before the collection completes (after CMS Initial Remark but before CMS reset), the old gen collection is not able to clear much memory. And as soon as this collection completes, another old gen gc is triggered. And in worst case scenarios, this cycle of old gen gc triggering, GC allocation failure keeps happening, and the old gen memory keeps increasing, leading to a single threaded STW GC, which is not able to do much, and I have to restart the solr server. The last time this happened after the following sequence of events: 1. We optimized the bigger collection bringing it to its optimized size of ~10G. 2. For an unrelated reason, we had stopped indexing to the master. We usually index at a low-ish throughput of ~1mil docs/day. This is relevant as when we are indexing, the size of the collection increases, and this effects the heap size used by collection. 3. The slaves started behaving erratically, with old gc collection not being able to free up the required memory and finally being stuck in a STW GC. As unlikely as this sounds, this is the only thing that changed on the cluster. There was no change in query throughput or type of queries. I restarted the slaves multiple times but the gc behaved in the same way for over three days. Then when we fixed the indexing and made it live, the slaves resumed their original gc pattern and are running without any issues for over 24 hours now. I would really be grateful for any advice on the following: 1. What could be the reason behind CMS not being able to free up the memory? What are some experiments I can run to solve this problem? 2. Can stopping/starting indexing be a reason for such drastic changes to GC pattern? 3. I have read at multiple places on this mailing list that the heap size should be much lower (2x-3x the size of collection), but the last time I tried CMS was not able to run smoothly and GC STW would occur which was only solved by a restart. My reasoning for this is that the type of queries and the throughput are also a factor in deciding the heap size, so it may be that our queries are creating too many objects maybe. Is my reasoning correct or should I try with a lower heap size (if it helps achieve a stable gc pattern)? (4. Silly question, but what is the right way to ask question on the mailing list? via mail or via the nabble website? I sent this question earlier as a mail, but it was not showing up on the nabble website so I am posting it from the website now) -----------------------------------------------------------------
