Hi All

We are running Linux with FB 1.53 classic
Linux CHERYL 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 12:03:43 EST 2008 i686 i686 i386 GNU/Linux

We had a backup job fail last night with an interesting error :

I rebooted, and now can create a new backup, but when i try to restore it i get the following :

root@CHERYL bin]# ./gbak -R -user x -pas x /opt/firebird/drdbase.gbk /opt/firebird/drdbasetmp.fdb
gbak: ERROR: System memory exhausted
gbak: Exiting before completion due to errors
Segmentation fault

I Restored i copy using IBOConsole from a Windows PC and that seems to have worked

Anyone any ideas?
