Out of memory error when doing a backup operation.

Action Plan

The problem is due to the fact of using a 32-bit server to do the backup operation. The 32-bit OS has a limitation of only using 2 G of memory, so if you have a backup which is taking up a lot of memory you can hit this limit. 

The solution is to

  1. Do the backup on the 64-bit database server either with the CAST CSS administration tools on windows or the postgres backup tools on Linux.  CAST 7.2 and above requires that you use a 64-bit database server for CSS and Postgres.
