Processes within ASE (sp_who), or the OS?
A long time ago (around 1998, or ASE version 10) Sybase had a product called Omni Server. The functionality for it was rolled into ASE where it now forms the CIS (component integration services) layer (proxy tables, proxy databases) - essentially functionality that allows sources of data on remote servers, including database systems from other vendors, to appear as local tables. Can't be sure that is what you are seeing though; and I don't know what the "-122" would mean.
