Vinod Kone created MESOS-244:
--------------------------------
Summary: Mesos webui process is not doing FLO_EXEC
Key: MESOS-244
URL: https://issues.apache.org/jira/browse/MESOS-244
Project: Mesos
Issue Type: Bug
Reporter: Vinod Kone
This appeared in one of our clusters at Twitter.
Looks like the slave webui process (which is a fork of mesos-slave) is not
properly doing FD_CLOEXEC, because we see a bunch of shared file descriptors
between slave webui and the executors.
