Summary: Memory Leak /High Memory usage post 3.11.2 upgrade Key: CASSANDRA-14495 URL: https://issues.apache.org/jira/browse/CASSANDRA-14495 Project: Cassandra Issue Type: Bug Components: Metrics Reporter: Abdul Patel Hi All, I recently upgraded my non prod cassandra cluster( 4 nodes single DC) from 3.10 to 3.11.2 version. No issues reported apart from only nodetool info reporting 80% usage . I intially had 16GB memory on each node, later i bumped up to 20GB, and rebooted all nodes. Waited for an week and now again i have seen memory usage more than 80% , 16GB + . this means some memory leaks are happening over the time. Any one has faced such issue or do we have any workaround ? my 3.11.2 version upgrade rollout has been halted because of this bug. =================================================================== ID : 65b64f5a-7fe6-4036-94c8-8da9c57718cc Gossip active : true Thrift active : true Native Transport active: true Load : 985.24 MiB Generation No : 1526923117 Uptime (seconds) : 1097684 Heap Memory (MB) : 16875.64 / 20480.00 Off Heap Memory (MB) : 20.42 Data Center : DC7 Rack : rac1 Exceptions : 0 Key Cache : entries 3569, size 421.44 KiB, capacity 100 MiB, 7931933 hits, 8098632 requests, 0.979 recent hit rate, 14400 save period in seconds Row Cache : entries 0, size 0 bytes, capacity 0 bytes, 0 hits, 0 requests, NaN recent hit rate, 0 save period in seconds Counter Cache : entries 0, size 0 bytes, capacity 50 MiB, 0 hits, 0 requests, NaN recent hit rate, 7200 save period in seconds Chunk Cache : entries 2361, size 147.56 MiB, capacity 3.97 GiB, 2412803 misses, 72594047 requests, 0.967 recent hit rate, NaN microseconds miss latency Percent Repaired : 99.88086234106282% Token : (invoke with -T/--tokens to see all 256 tokens) -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
