Hi,

we ran into the situation a few weeks ago,
but this problem can easily be fixed.

This is the standard setting for AIX ulimits:

prompt> ulimit -a
time(seconds)        unlimited
file(blocks)         2097151    <=== Max. File size < 1GB
data(kbytes)         131072
stack(kbytes)        32768
memory(kbytes)       32768
coredump(blocks)     2048

Just set new ulimits before working with ADSM/formatting database files,
e.g.

prompt> ulimit -f 4194304

for a filesize up to 2 GB.

Bye,
/dh
