Issue with mbuf de-allocation when using NFS in RTEMS

I did see this patch, it looks like it is to do with fixing the issue with the RPC cant decode. We will see if it fixes this, but why would the MBUF count go down due to this? Have you seen anything that would indicate a reason for the MBUF not being freed.

It seems you are not alone with the issue on the 4.9 series. Till references ticket #1775 in the second link which is in Trac, see https://devel.rtems.org/ticket/1775. There are patches attached which might be worth looking into.
