Jeff Griffith commented on CASSANDRA-10515: ------------------------------------------- [~mishail] [~blambov] thread dump attached. > Commit logs back up with move to 2.1.10 > --------------------------------------- > > Key: CASSANDRA-10515 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10515 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: redhat 6.5, cassandra 2.1.10 > Reporter: Jeff Griffith > Assignee: Branimir Lambov > Priority: Critical > Labels: commitlog, triage > Attachments: CommitLogProblem.jpg, CommitLogSize.jpg, stacktrace.txt, > system.log.clean > > > After upgrading from cassandra 2.0.x to 2.1.10, we began seeing problems > where some nodes break the 12G commit log max we configured and go as high as > 65G or more before it restarts. Once it reaches the state of more than 12G > commit log files, "nodetool compactionstats" hangs. Eventually C* restarts > without errors (not sure yet whether it is crashing but I'm checking into it) > and the cleanup occurs and the commit logs shrink back down again. Here is > the nodetool compactionstats immediately after restart. > {code} > jgriffith@prod1xc1.c2.bf1:~$ ndc > pending tasks: 2185 > compaction type keyspace table completed > total unit progress > Compaction SyncCore *cf1* 61251208033 > 170643574558 bytes 35.89% > Compaction SyncCore *cf2* 19262483904 > 19266079916 bytes 99.98% > Compaction SyncCore *cf3* 6592197093 > 6592316682 bytes 100.00% > Compaction SyncCore *cf4* 3411039555 > 3411039557 bytes 100.00% > Compaction SyncCore *cf5* 2879241009 > 2879487621 bytes 99.99% > Compaction SyncCore *cf6* 21252493623 > 21252635196 bytes 100.00% > Compaction SyncCore *cf7* 81009853587 > 81009854438 bytes 100.00% > Compaction SyncCore *cf8* 3005734580 > 3005768582 bytes 100.00% > Active compaction remaining time : n/a > {code} > I was also doing periodic "nodetool tpstats" which were working but not being > logged in system.log on the StatusLogger thread until after the compaction > started working again. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
