Problem IT31807 | Status: Closed |
EXCESSIVE MEMORY USAGE DURING ARCHIVE WHEN CHUNK CONTAINS 2,147,483,647 PAGES | |
product: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
Problem 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 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.
