Re: DLMALLOC PANIC LINE 3503


 

It sounds like this mystery code is a REXX function package from a non-VM system.

If that is true, then the best we could do here would be to fail more gracefully.?
The DLMALLOC msg indicates a storage problem to me. Perhaps an overlay.

Bert,

As far as I can tell the sys functions are an add-on package on all CMS.

On LCM+l which is a later VM/CMS but not real iron, it fails gracefully, but support for external functions was only just added to 1.1.2.

Lets see what Bob says, he is on a different time zone.

Dave,

?

So none of the sys functions exist in CMS REXX???

?

Should REXX blow up this way?? How did it blow up on your real iron system?

?

I'm not sure REXX is ready for what I need.? Sys functions are basic to me.

Bert,

What makes you think RxFuncQuery and RxFunctionAdd work in CMS?

It also fails on the SP5 system at LCM+L

Hello,

?

On the earlier problem, I decided to add some tracing to determine the line causing the DMSIPT143T error.? What I got was:

?

DLMALLOC PANIC LINE 3503

ABNORMAL TERMINATION (NO RESOURCE CLEANUP) ERROR 430 DLMalloc aborted.

Ready (00012);

?

The program now looks like

/* */

trace 'e'

? ? ?if RxFuncQuery( 'SysLoadFuncs' ) <> 0 then
? ? ? ? ?do
? ? ? ? ? ? call RxFuncAdd 'SysLoadFuncs', 'REXXUTIL', 'SysLoadFuncs'
? ? ? ? ? ? call SysLoadFuncs
? ? ? ? end
a = 0
do forever
? a = a + 1
? say a
? if a//20 = 0 then do
? ? 'cls'
? ? rc = syssleep(1)
? ? end
? end

?

P.S. Where should I report this problem (e.g. URL) and should it be against REXX or CMS or ????

?

Thank you.
