Error in selection of clob data

Hello Everyone

I am running a select on a hana table which contains clob data. But i receive some notification regrading persistence

Could not complete result operation. SAP DBTech JDBC: [21]: persistence error: exception 70029020: ltt::exception caught while operating on DISK_NCLOB:2:1090921698160exception 1000002: Allocation failed ; $size$=10485760; $name$=PersistenceLayer; $type$=pool; $inuse_count$=6580; $allocated_size$=5444213184 at function __copy__()

Does anyone have any idea to tackle this issue?

Thanks in Advance

Best Regards

Vivek
