Backup server fails with Illegal max-length for parameter #3 for RPC as_arch_device

Hi

I've just installed a new copy of ASE 15.7 (SP100) on a CentOS 6.5 server.

ASE appears to work fine, but the backup server fails with "Illegal max-length for parameter #3 for RPC as_arch_device" when I try to run a dump database (or load database) command.

CentOS 6.x maps to the corresponding RH EL 6.x versions. I haven't checked if ASE is certified on RH EL 6.x - maybe I'm being a little ambitious in using this latest distro...

Any info/help would be appreciated (of course :-)

Thanks,

Michael
