Hi Mohan
When I googled RNX1251, I received a number ofresponses, but this one caught my eye
https://itknowledgeexchange.techtarget.com/itanswers/how-to-ignore-permanent-io-error-on-a-display/
is it possible that the problem is caused by an undisplayable character

Subject: RPG program halting with RNX1251 Permanent I/O error occurred in DISPLAY file
Hello
I have an RPG that displays a subfile.
After some user action, i call another program that has it's own DSPF. This way there are 4 to 5 programs called with their own DSPF. And all screens have been compiled with Restore display RSTDSP(*YES) attribute.
When control returns to my 1st program, I am displaying a WINDOW without using any of these keywords CLRL, OVERLAY, PUTOVR, PUTRETAIN, ERRMSG, or ERRMSGID.
But program fails with below message on EXFMT of the Window record format.
What do you suggest ?
This failure does not happen all the time. Happens sporadically.
The major return code is 80.
Message ID . . . . . . : RNX1251 Severity . . . . . . . : 99
Message type . . . . . : Escape
Message . . . . : Permanent I/O error occurred in file INPR410S.
Cause . . . . . : RPG procedure INPR410R in program PRODUCTION/INPR410R
detected a permanent (not recoverable) file, session, or device error.
The
session, device and/or program has been stopped. Examine the major/minor
return code value to determine the specific error that occurred. If the
major return code is 80 then a system or file error occurred and programmer
action is required to fix the problem.
