strpccmd all of the sudden doesn't work anymore

Question

We have a program with the next lines:

// Editor voor blob opstarten
@cmdString = 'STRPCO';
callp(e) excCmd(@CmdString :%len(@CmdString));

@cmdString = 'STRPCCMD PCCMD(' + '''' +
             'CMD /C START ' +
             '\\' + %trim(@systeemNaam) +
              %trim(@blob_name) +  ''''  +
              ') PAUSE(*NO)';
excCmd(@CmdString :%len(@CmdString));

The value of @cmdString in the bottom line has the value:

STRPCCMD PCCMD('CMD /C START \SYSTEMNAME>/INPUT/PZ/TEMP/<DocumentName.doc') PAUSE(*NO)

This command opens the document in word. But after 9 years and 2 months all of a sudden it gaves this error and when the users click OK the RPG error runs in an error enter image description here

There are few odd things:

• when I debug the program to avoid that the programs runs in an error and starts the function to open the word document again, it opens fine. And it works fine as long as I not close this specific session
• When I open a new session, which normally gives an error when calling this function, and insert a breakpoint at the second last line and wait there for a few second and hit F12 then the word document opens fine.

Till now I can't find the cause of this error. This someone has an idea?

Debugging and check the authorities on the IBM i and the IFS. The authorities didn't change compared to the situation before the disruption.
