This is what transpired. There are triggers based upon the table identified. Reviewing the text, there are INSERTED rows to some table. A couple of clues. The number of INSERTED and UPDATED are equivalent (1 INSERT for 1 UPDATE). The TR_MAIN_TIME and TR_MAIN_CPU columns contain values which contain stats on Triggers, and SYSIBM.SYSTRIGGERS contains rows for the table in question.
