FCS error

FCS stands for Frame Check Sequence. Each PPP packet has a checksum attached to ensure that the data being received is the data being sent. If the FCS of an incoming packet is incorrect, the packet is dropped and the HDLC FCS count is increased. The HDLC error values can be displayed using the show hdlc command.

LSF job

LSF - Load Sharing Facility - is a system to manage (large) programs that cannot be run interactively on a machine as they require too much CPU-time, memory or other system resources. For that reason, those large programs have to be run in batch (batch jobs). [1]
More details refer to [1].
