APAR status
Closed as program error.
Error description
The maximum number of pages in a chunk is 2,147,483,647 (0x7fffffff). Archiving a dbspace with a chunk of this size can use an excessive amount of memory when starting the archive and there is a reasonable chance it will fail with an error comparable to: CDR 4026531841 byte memory allocation failed (Pool:arc_4667763 Thread:ontape). Assert Warning: ISAM error: An error has occurred during archive back up. IBM Informix Dynamic Server Version <version> Who: Session(4667763, user@host, 37903, 0xf0d4caf8) Thread(5315619, ontape, 1f56c9988, 19) File: rsarcutl.c Line: 115 Action: init_arcbu()/SCBMALLOC() stack trace for pid 97815 written to DUMPDIR/af.200bc8f8 See Also: DUMPDIR/af.200bc8f8 ISAM error: An error has occurred during archive back up.

Local fix
Configure the instance to allow it to use up to an additional 4GB of memory for the archive.
