Under the high-load situation, the "cupsPrintFiles" function sometimes returns zero without being set any error code into the last_error. Around the line #1419 of cups/util.c, when the "ippFindAttribute" function returns a NULL pointer, I guess, the last_error should be set, however no error code isn't set to it.
