I am working on Linux 3.2.0.

Wow, you're still developing on a kernel that is 4.5 years old and
you're not even taking the stable updates.

since we did development with phyCORE-AM335x-PD13.1.2 which is using 3.2 kernel.
we have already completed production and it wont be a easy task to
shift to 4. series

We had a requirement to make Linux Real Time so using RT-PREEMPT
(patch-3.2-rt10.patch.bz2)

Even if you stick to 3.2.x, there is 3.2.82-rt118.

We are facing a network hang issue while running the periodic task of 5 ms.

cannot ping any more when task is running is ran for some time.

I am using Timer fd protocol to achieve this.

I would like to know if there is such know issue in this patch.

Any help will be appreciated.

I bet you won't find help here until you reproduce the issue with a
recent kernel (currently there is v4.6.7-rt11) and show the code of your
periodic task.

I am using iperf to transfer the data over network same problem of
network hang happens
cannot ping any more.

Attached code for rt task

Best regards
Uwe
