Hudson commented on MAPREDUCE-3333:
-----------------------------------

Integrated in Hadoop-Hdfs-0.23-Build #72 (See [https://builds.apache.org/job/Hadoop-Hdfs-0.23-Build/72/])
    MAPREDUCE-3333. Fixed bugs in ContainerLauncher of MR AppMaster due to which per-container connections to NodeManager were lingering long enough to hit the ulimits on number of processes. (vinodkv)

> [~Karams] just found this. The usual sort job on a 350 node cluster hung due to OutOfMemory and eventually failed after an hour instead of the usual odd 20 minutes.
