I have some idea: if there are bridges between sending and
receiving host, it is possible some bridge loses packets
in case few ones are sent without delay, due to same error
in the bridge functioning. Is it possible in your network?

Such an error may be: one of receivers requires some delay
between end of one packet and start of the next, and the
transmitter which sends to it sends with smaller delay.
Of course there are standards, and as far as they are met
it is impossible, but a question is if they are met.
Other possibility is that such a bridge has insufficient
buffer to store next packet while previous is still kept.

Regardless of what is the reason, a method to find source
of the problem is analysing packets on various places on
the cable. Maybe it is good idea to check error counters
on sending and receiving hosts before doing it, for a case
the malfunctioning device is net device of any of them.
