Hi Dilip
When posting here, please always include the ASE version used as this provide vital information that is almost always relevant.
The output includes : "Data Protector" so it seems you use a HP backup utility and from that it seems feasible you are running ASE on HP OS with an SAP application.
The messages point to a known issue :
KBA 2099194 - SAP ASE Backup Server on HP-UX may die with error messages: A00: SYBMULTBUF ERROR: Emulator interprocess communication failed with error state = 1
http://service.sap.com/sap/support/notes/2099194
There is no workaround for this. Fixed from these releases :
SAP ASE 15.5 ESD 5.4
SAP ASE 15.7 SP63
SAP ASE 15.7 SP130
SAP ASE 16.0 SP01
