getting 4837 while using DB lib on sybase 15.5 AIX5.3

[Vijay]

HI Gurus,


We have recently migrated Gloss HK databasefrom Sybase ASE 12.5 to
Sybase ASE 15.5. After the migration we are intermittentlygetting
below errors. The speciality is if we re run the job the transaction
gets successful. Our DR server is still on ASE 12.5, we have a
replication link between live (15.5) and DR (12.5) servers

we are on AIX 5.3, using DB LIB

Do you have any inputs on the below.
