sybprocsdev is the default name for this device. However, it is frequently referred to as the sybsystemprocs device, as in the Adaptive Server attribute window, since it stores the sybsystemprocs database.
Verify that the sysystemprocs database is large enough. For an upgrade, the recommended minimum size for sybsystemprocs is the larger of 132MB, or enough free space to accommodate the existing sybsystemprocs database, and the largest catalog that is to be upgraded, plus an additional 10 percent for logging upgrade changes. You may need more space if you are adding user-defined stored procedures. 124MB accommodates additional internal data structures, but does not account for the possibility of a larger number of user-defined system procedures. For instructions on increasing the size of the sybsystemprocs database see Appendix E, “Using sybsystemprocs.”
