Duplicate inodes

[Jay Naik]

I have a Sun/SLC, running Sun OS 4.1.1. I create large files (160,000
bytes/file), at the rate of about 5 files/minute. These files are created
on the local system disk and then written out over the network to another
client machine (sun 4/260). 

I also have an A/D (Analog-to-Digital) converter hanging off the SCSI bus,
which pumps binary data to the system disk over the SCSI bus at the rate
of 64 kbytes/sec.

My file-system is frequently getting corrupted, with duplicate inodes. The
corrupted files are different each time, with no clearly discernible
pattern.

Could someone shed light on this mys(mess)tery? Any suggestions??
