We had this problem and we solved it changing the configuration of the OSA-
ICC card. Using the HMC console, under Single Object = Advanced
Facilities = Channels = Card Specific Advanced = Session Configurator,
we changed Response Mode to DISABLE.
Here is the explanation from book SA22-7990
This past January we upgraded from a z/800 with 2074's to a z/890 with
OSA-ICC's. For the first two month's or so our consoles for z/OS 1.6 ran
fine, just like they used to on the 2074's. For about the last 3-4 weeks
they have been behaving very slow. Our operators have been complaining
The only time I've noticed this behavior is when our OSA was set to auto
negotiate and connected at 10MB-half duplex. Hope this helps.
