             Summary: Each new thread creates a PIPE and KQUEUE as open files 
during producer.send() and does no0t get cleared when the thread that creates 
them is cleared.
                 Key: KAFKA-1745
                 URL: https://issues.apache.org/jira/browse/KAFKA-1745
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8.1.1
         Environment: Mac OS Mavericks
            Reporter: Vishal
            Priority: Critical


Hi,
    I'm using the java client API for Kafka. I wanted to send data to Kafka by 
using a producer pool as I'm using a sync producer. The thread that sends the 
data is from the thread pool that grows and shrinks depending on the usage. So, 
when I try to send data from one thread, 1 KQUEUE and 2 PIPES are created (got 
this info by using lsof). If I keep using the same thread it's fine but when a 
new thread sends data to Kafka (using producer.send() ) a new KQUEUE and 2 
PIPEs are created.

This is okay, but when the thread is cleared from the thread pool and a new 
thread is created, then new KQUEUEs and PIPEs are created. The problem is that 
the old ones which were created are not getting destroyed and they are showing 
up as open files. This is causing a major problem as the number of open file 
keep increasing and does not decrease.

Please suggest any solutions.
