TSN <num>:<num> error count exceeded <num> failure threshold Explanation: The number of AIJ optimize errors exceeded the transaction error threshold specified by the <fac>$BIND_OPT_TXN_THRESHOLD logical name. This is not a fatal error. User Action: None. The remainder of the transaction contents are written directly to the optimized AIJ file. Use of the <fac>$BIND_OPT_TXN_THRESHOLD logical name may actually increase the AIJ optimize operation performance as the number of required sort operations is reduced. However, this may result in a larger output file.
