(from CIB merge version 3.9.174)

The parameter maxSingleSize sets the maximum allowed size for a single document in the "serialletter" case.

Syntax

--maxSingleSize=[#bytes]

Description

This parameter is an abort criterion for merge letters created with CIB merge. If a single document of a mail merge letter is larger than the set maximum size, CIB merge acknowledges this with a return code 817.

This allows the user to make sure that the creation (which usually happens automatically and without human control) is aborted if unwanted behavior in the file size range occurs.
