SYMPTOM(s):

4GL/ABL: Errors (491), (2873) and (2869) running a 4GL/ABL application

SYSTEM ERROR: bfsort.c: fatal error <error-number> (491)

Cannot change cursor of buffer <buffer> when executing a trigger. (2873)

Attempt to disconnect a <table> record, which is running a trigger. (2869)

Application involves a browse widget against a large table with lots of fields.

Application startup command involves a .ini file.

The .ini file does not involve MultitaskingInterval parameter.

Errors happened only once and can not be reproduced.

FACT(s) (Environment):

Windows
Progress 8.x
Progress 9.x
OpenEdge 10.x

CAUSE:

The errors are caused by a collision between the Progress application and some other non Progress Windows application running at the same time. The Multitasking Interval setting is the most likely culprit.

FIX:

If the the above set of errors persist, then remove the MultitaskingInterval=n from the .ini if any and/or set the SESSION:MULTITASKING-INTERVAL to an appropriate non-zero value that would balance between the application's performance and its stability.
