longfei commented on MESOS-9852: -------------------------------- [~bmahler] I used jemalloc, which resulted in less memory usage(about 500MB of master). But after running some time, it grew to about 1GB. [^statistics] is the output of the memory-profiler/statistics endpoint. ^[^_tmp_libprocess.Do1MrG_profile (1).dump] is a 2-mins profiling result.^ ^The newest commit is 8e8c6c0.^ ^OS: Debian stretch with kernel 4.14.81.bm.11-amd64^ > Slow memory growth in master due to deferred deletion of offer filters and > timers. > ---------------------------------------------------------------------------------- > > Key: MESOS-9852 > URL: https://issues.apache.org/jira/browse/MESOS-9852 > Project: Mesos > Issue Type: Bug > Components: allocation, master > Reporter: Benjamin Mahler > Assignee: Benjamin Mahler > Priority: Critical > Labels: resource-management > Fix For: 1.5.4, 1.6.3, 1.7.3, 1.8.1, 1.9.0 > > Attachments: _tmp_libprocess.Do1MrG_profile (1).dump, > _tmp_libprocess.Do1MrG_profile (1).svg, screenshot-1.png, statistics > > > The allocator does not keep a handle to the offer filter timer, which means > it cannot remove the timer overhead (in this case memory) when removing the > offer filter earlier (e.g. due to revive): > https://github.com/apache/mesos/blob/1.8.0/src/master/allocator/mesos/hierarchical.cpp#L1338-L1352 > In addition, the offer filter is allocated on the heap but not deleted until > the timer fires (which might take forever!): > https://github.com/apache/mesos/blob/1.8.0/src/master/allocator/mesos/hierarchical.cpp#L1321 > https://github.com/apache/mesos/blob/1.8.0/src/master/allocator/mesos/hierarchical.cpp#L1408-L1413 > https://github.com/apache/mesos/blob/1.8.0/src/master/allocator/mesos/hierarchical.cpp#L2249 > We'll need to try to backport this to all active release branches. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
