8.1.7 Linux: strange Harddisk activity

hi,
on 8.1.6 and 8.1.7 Enterprise Edition
on Linux (SuSE 7.0) I found a strange behaviour:

after the change from _nomount_ to _mount_ (the same as to _open_)
there is a rhytmic harddisk-activity every second. rdrdrd .....1 second silence ..... rdrdrd .....

• with and without a Listener running
• 256 MB RAM, unused Swapfile
• no network active.
• alert log shows no errors, except this: Load Indicator not supported by OS !
• all background processes show zero-activity soon after startup, so I cannot identify one of them.

This is specific to the Linux-Installation. I played around with 8.1.5 and 8.1.6 Enterprise on Windows NT 4 and NT 5 and found nothing
of that kind.

I thought of SMON rearranging blocks in the datafiles. But this behaviour lastet for hours on an idle database with almost nothing but system tablespace.

any ideas ?
