Yes, it is a good thought and I will get new traces to verify.
The previous network traces showed all the packets being ACK'ed. The Remote
devices (Vocollect Talkmans) sends 129 bytes of data and the 400 (yes, I
refer to it as a 400 as I do not want to keep up with the many names it was
called the past 20 years, please forgive me) is supposed to reply back with
a single Y. We could not detect any differences in the packets when it was
a good, processed transmission to when it delays the transmission.
I'll create new traces to be sure, but the network looks solid.
On another note: the delay issue went on for 15 continuous minutes today
causing a work stoppage. CPU was over 100% this time, but other times it is
not. The remote devices (Talkmans) packets where making it all the way to
the host, NETSTAT *CNN showed a connection, but no job was associated with
it. The listener program never knew of their existence.
Please be sure, your advice is greatly appreciated

This is a good thought... packet loss would definitely cause an issue like
this.

Are there any retries happening? Can you PING the devices with a rock
solid (NO LOSS) ping in low double digit response times? Any packet
loss will cause retransmits which can clobber response times. You say
the connections are appearing in the comm trace so this may be OK, just
askin.
