Web problems with Multinet 5.2

(also sent to ***@process.com, but maybe some of you have some idea.)

VMS 8.3, patched to current as of last week
Alpha DS20E
Multinet 5.2 - patched to current as of 12/31
(eg: )

$ multinet config
MultiNet Network Configuration Utility V5.2(107)

We're suddenly finding (reports this week, but it might have been there last
week) that pages and files downloaded from our web server are corrupted. (Zip
files that don't unpack; web pages that lose formatting or don't display.)
Internet Explorer sometimes reports that it can't find our server; a reload
usually fixes that. (Bizarrely, https:// works when http:// doesn't, so it
might be an issue with port 80 specifically.)

It seems to happen sporadically (one of three tries) on large files, not
necessarily at all on small files.

The same files download through FTP with no problem. We're not seeing random
characters in our SSH terminal connections.

Another cluster member (an Itanium box) running the same version of Apache is
running TCP/IP services; it doesn't show these problems. Another cluster
member (an Alpha box, shares the system disk) does show these problems.

I installed Multinet 5.2 over the holiday shutdown and put up all the patches
then available.

This is something of a showstopper for us. Please advise.

Thanks!

Sounds like you should get the lateset UCX_LIBRARY_EMULATION eco which is
currently UCX_LIBRARY_EMULATION-070_A052.

Things are weirder than they appeared to be. I already have that patch
installed. I hadn't restarted Apache, so I had the old UCX$IPC_SHR mapped
even though the new one was installed. On one system, I restarted Apache, and
the problems went away.

On the production system, restarting Apache didn't fix the problem, and neither
did rebooting.

But I've got the patch there too:

Am perplexed.
