longfei commented on MESOS-9852: -------------------------------- Some information: !screenshot-1.png! The above image shows memory usage of a mesos master(version 1.7.3) we used in production environment. After a little dig(with pmap), I found that some anon mem blocks(with a size of 65536 KB) are allocated and the number is growing. > 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: screenshot-1.png > > > 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)
