Xenix 2.1.3 slowdown on 286 clone

[compata at cup.portal.com]

Several of my customers are running Xenix 2.1.3 on a 1 MB AT clone.  They have
complained that the system seems to begin running more slowly after it has
been up for several days.  Even to the point where response to a haltsys
requires ten minutes.  The problem can be easily cured by rebooting.

I would consider suggesting that they upgrade to 2.2 if I can be confident
that it will fix the problem.  Is this a known problem with 2.1.3?  Is it
fixed in 2.2?  Is it perhaps caused by some data structure accumulating,
eventually filling memory?

I know that an upgrade would require that they also purchase more memory,
at least 1 more MB.  They are running a MS-COBOL application from 3-5
concurrent terminals, so the problem could also be in COBOL.  It certainly
does have problems.  Does anyone have any suggestions?
