The files are images > slightly less than 1 MB and a thumbnail (approx. 983000 files). Replying once more to my own mail. There seems to be a hardware-related problem to my setup. I'm getting some 'arcmsr0: scsi id=1 lun=4 ccb='0xffffff02d5cc8e00' outstanding command timeout' (in solaris). I'll check with my vendor. I did not see such errors in FreeBSD. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
