Subject Re: Coredump from Firebird 1.03 Server
Author josef_gschwendtner
we don't use UDF's nor Events
Backup is done each day
there is no antivirus program runing
there should be enough space for temp-file (2GB)
we don't know what the server is doing during the crash, because its
kind of a 24/7 system.

The database is around 2GB (at the moment). About 500000 records will
be inserted each day. The data insertion is done from a JBoss-Server
via JDBC (Jaybird 1.5.4) on a RedHat 7.2 system (Double XEON)

The data of one special table is needed only 30 days, so we delete
older data periodically (400000 records --> GC is very busy);
otherwise the database is getting to large.

Infos about the server-machine:
Linux version 2.4.20-28.7smp
Filesystem: EXT3 FS 2.4-0.9.19
Mount: EXT3-fs: mounted filesystem with ordered data mode.
The 64-bit file I/O version of Firebird is installed.
