             Summary: Memory leak in processing MCMP, wrong apr pool used for allocation
                 Key: MODCLUSTER-523
                 URL: https://issues.jboss.org/browse/MODCLUSTER-523
             Project: mod_cluster
          Issue Type: Bug
          Components: Native (httpd modules)
    Affects Versions: 1.3.1.Final, 2.0.0.Alpha1
         Environment: Solaris 10 x86_64, RHEL 6, Fedora 24, httpd 2.4.6, httpd 2.4.20
            Reporter: Michal Karm Babacek
            Assignee: Michal Karm Babacek
            Priority: Critical


There seems to be a wrong apr pool used for processing certain MCMP commands. We should use short life span pools for immediate processing and server-lifetime pools only for really persistent configuration.  In the current state, with 20+ tomcat workers (1 alias and 1 context each) and virtually no client requests, we could see slow, but steady growth of heap allocated memory.

TODO: Investigate the offending logic, make sure we ain't using long-lived pools for immediate processing.

Illustrative memory overview - with constant number of Tomcats:
