The datatypes for the spid column of these tables have been changed from smallint to int:
sysprocesses.spid
sysprocesses.fid
sysprocesses.blocked
sysprocesses.fid
syslocks.spid
syslocks.fid
sysaudits_01.spid - sysaudits_08.spid
syslogshold.spid
systransactions.spid
Because of this change in spid datatype, Sybase strongly recommends that you archive and truncate audit tables before you upgrade. This reduces the likelihood of a failed upgrade because of insufficient space in the sybsecurity database.
