I've seen this. It usually occurs on larger, more complex screens (which is
why we still have a couple of DECforms screens, many years after moving to PH).
It's alleviated by giving PH more memory and/or upgrading to 7.10.G3.
Note that there's several parameter sets to tweak for more memory:

The sysuaf (authorize) quotas (PGFLQUOTA & WS*)
The sysgen/autogen quotas (the PQL parameters, etc).
The QKGO execution time parameters.

You don't say what VMS you're running. SYSUAF & autogen are in the purview of
your system manager, but most modern systems are probably limited by the QKGO
parameters: VMS defaults to quite large quotas these days.

I still see these problems occasionally, but much less than I used to - if
anyone has a magic bullet, do tell. They're typically impossible to reproduce.
They seem to be associated with users re-entering the same field several times,
as a result of typos.

Alternatively, there could be something wrong with your C code ...
