@Peter, thanks.

It typically occurs after the program has been running for some time and
been through several WAIT/POST cycles.

FSVO "reported" <g>. I will bet you my own z/OS license that *LE* is
reporting it on the WAIT.

Did you consider the possibility that the ECB storage might not have been
initialized to 0's prior to the wait (and prior to the potential post)?
And perhaps the post happened before the wait. Imagine if the ECB storage is
initialized by "dirty getmain" to x'80808080'. This will appear to POST as
"waiting" but will not have a valid RB address and may result in a 202
abend.

POST.

Wanna bet?
