HANA & R-Integration - Execution of R script failed (cannot allocate vector of size)

Hello everyone,

we receive an error message when executing an R Script embedded inside a SQLScript Procedure. With smaller data sets, the procedure is working fine:

Could not execute 'CALL PAL.XXX.XXXX()' in 1:13.629 minutes .

SAP DBTech JDBC: [2048]: column store error:  [2048] PAL.XXX.XXXX: line 5 col 1 (at pos 126): GenericFailure exception: column store error: search table error:  [34082] Execution of R script failed.;Error: cannot allocate vector of size 280.5 Mb

stack trace:

No traceback available 

Does anybody know how to increase the max. size of memory allocated to our R script? Our R Server is installed on a separate SLES 11.3 32-Bit environment with 4GB of ram.

Thanks for helping and best regards,

Florian
