So, had something fun and interesting (sarcasm) happen to me today in the world of X3 V9.  When the source code hit my DBGAFF statement, I got errors about  "OPS: Sequential File Management Error"  and line 2064 of AXDTDBG.... when the code was "Seek 0 Using [OPS]" in the Subprog SEEK_SOCK()

to be honest, after all these years... this is my 1st time seeing this process, or this error.   When i turned off all the debugging parameters in Parameter Values, the error persisted... but when i removed the DBGAFF  it vanished.

so.. curious if anyone else has ever seen this, or what they make of it.

notes:

i did just try to debug another function, and that one triggered the debug without too much of an issue (eclipse is being cranky and not launching debug in my local, opened session, but that is, separate i believe)

The function giving me issues is custom.. but it has worked for YEARS without issue, and the only change i made was to add the dbgaff command , and i have debugged it in the past without issue.
