Hi

My system:
RISC System/6000 model F80 ( 4 proc 9BB RAM )
AIX 4.3.3 ML 11
Oracle 8.0.5

I have problem to crate files in filesystem (jfs) /oracle/PRD, it physically is on device FastT500
It is strange for me because df -k return information that
tere is 18 GB free memory:
Status of volume group where logical volume resides is:
PP SIZE: 512 megabyte(s)
TOTAL PPs: 676 (346112 megabytes)
FREE PPs: 116 (59392 megabytes)
USED PPs: 560 (286720 megabytes)
Any user in OS which want crate, read, execute files have nolimits, ulimit -a:
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) unlimited
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) unlimited
The files for DB oracle are smaler than 2GB

The problem is occasionaly, once I can create file in the next time I can't.
If I can't create a file system the system return errors:
IBM AIX RISC System/6000 Error: 12: Not enough space
Additional information: 2

The problem occures for create diffrent kind of files, examples:

ORA-01580: error creating control backup file /oracle/PRD/sapbackup/cntrl.dbf
ORA-27044: unable to write the header block of file

vi test.txt ( in directory /oracle/PRD )
cp file1 file2( in directory /oracle/PRD )
mv file1 file2( in directory /oracle/PRD )

After above errors I can't read files or logs from /oracle/PRD. Even the try to remove file from /oracle/PRD return error:
IBM AIX RISC System/6000 Error: 12: Not enough space

In eerpt (after write fail) are information that filesystem /oracle/PRD
require full fesk.
There is no any informations about hardware problem.
IBM support have my snap - their responce " YOUR HARDWARE IS OK ! "
Additionaly I have applyied the newest microcode and firware to all componets F80 and FastT500.
After fsck -y /oracle/PRD the system works properly to next down :(

HELP :(((
