GBAK fails for big tables with BLOBs
------------------------------------
Key: CORE-4845
URL: http://tracker.firebirdsql.org/browse/CORE-4845
Project: Firebird Core
Issue Type: Bug
Components: GBAK
Affects Versions: 2.5.2
Environment: Windows 2003/7/etc, 32bit
Reporter: Alex Gilev
While performing backup for big database (about 90 Ggb) GBAK fails with error:
gbak:error accessing BLOB column EXT_INFO -- continuing
gbak: ERROR:unable to allocate memory from operating system
It stops working after writing about 10 millions records, Firebird "eat" at
this moment about 2Ggb memory. Tested with Firebird 64 at another PC and it
perfomed backup well.
We have about 20 PCs with such databases and Windows 32bit (so Firebird 32 bit
too) and it's not very easy to migrate all this PCs to Win64. Maybe it's
possible to make some fix in Firebird to "eat" less memory while perform such
backups?
