Hello!
I run Amanda under FreeBSD-4.11, so when Amanda trying to make file of
dump with size of more than 4GB (exactly, 2**32-1), i can see in
log/amdump.* the following messages:

That is due to filesystems constraints in FreeBSD-4.x where a size of
file is given in 32-bit representation and declared in sys/stat.h with
int32_t integer type.
Is there passible to change some code of Amanda to do the dumps into more
than 4GB files under FreeBSD-4.x? (for example, with deal of stdout) Where
in the Amanda code the conditions are checking for the maximum length of
writing file?

Are you "taping" to virtual tapes on hard disk?  If so, and your version
of amanda is recent, us the tape splitting feature that writes in chunks
than can, but don't have to, span several tapes.

If using a holding disk, use the chunk size feature to limit the maximum
size of a file on holding disk.

Yes, i'm taping to hard disk (tapedev=file:/). Actually the problem arises
when the dump itself is finished and all chunks (in my config chunksize =
256MB) are beginning to be sent from holding disk to file in storage
directory. And when this file reaches 4GB Amanda dropping errors such as
[writing file: File too large] into log. Mayby there are some ways to
solve the problem of under FreeBSD-4.x system?
I have Amanda of version 2.5.1p3.
