Unanswered: Backup Server error during dump to nfs device
I have two AIX 5.2 machines with Sybase ASE 220.127.116.11 and on both of them I mounted an OSX nfs share. The "sybase" user ulimits for file, data and core are "unlimited" on both AIX machines and it was set via smit. From one machine I can dump the whole 30G to the nfs mount without a hitch. From the other one dump fails at 1GB:
1> dump database sur to "/morrow1mfs/sur.dat" with init

Msg 8009, Level 16, State 1:

I even set directly the hard limits of file, data and core on this failing machine without success.
