[jira] [Updated] (MESOS-6420) Mesos Agent leaking sockets when port
mapping network isolator is ON
[ https://issues.apache.org/jira/browse/MESOS-6420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jie Yu updated MESOS-6420:
--------------------------
Summary: Mesos Agent leaking sockets when port mapping network isolator is ON (was: Mesos Agent leaking sockets when network isolation is ON)
> Mesos Agent leaking sockets when port mapping network isolator is ON
> --------------------------------------------------------------------
>
> Key: MESOS-6420
> URL: https://issues.apache.org/jira/browse/MESOS-6420
> Project: Mesos
> Issue Type: Bug
> Components: isolation, network, slave
> Affects Versions: 1.0.2
> Reporter: Santhosh Shanmugham
>
> Mesos Agent leaks one socket per task launched and eventually runs out of sockets. We were able to track it down to the network isolator (port_mapping.cpp). When we turned off the port mapping isolator no file descriptors where leaked. The leaked fd is a SOCK_STREAM socket.
