server_bulk_callback signals the completion of bulk data movement
initiated by servers; type 2 and 4 are for bulk read and write
operations (from the perspective of the server) respectively.

The -103 error most likely came from Lustre networking stacks. You'd
be able to get more details by enabling low-level network error
console logging:
echo +neterror > /proc/sys/lnet/printk

Thanks,
