Subject [jira] [Updated] (DISPATCH-337) Huge memory leaks in Qpid Dispatch router
Date Fri, 03 Jun 2016 01:32:59 GMT

     [ https://issues.apache.org/jira/browse/DISPATCH-337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vishal Sharda updated DISPATCH-337:
-----------------------------------
    Attachment: Subsequent_memory_increase.png
                Rapid_perm_memory_increase.png

Two files attached: Rapid_perm_memory_increase.png and Subsequent_memory_increase.png

We ran two interconnected routers having 2-way SSL connection between them and accepting 2-way
SSL connections from clients.  We connected several senders to one router and several receivers
to the other.  Total of 250K messages were sent from one end to the other.  We saw  rapid
increase in memory usage of both the routers.  This memory never became low again and a subsequent
identical run increased the memory further.

Since the routers are never intended to be terminated, such memory leaks on all subsequent
connections and data transfers will eventually lead to routers being killed.

> Valgrind shows huge memory leaks while running 2 interconnected routers with 2 parallel
senders connected to the one router and 2 parallel receivers connected to the other router.
> The CRYPTO leak that is coming from Qpid Proton 0.12.2 is already fixed here:

> However, the rest of the leaks are from qdrouterd.
