Some more news about my problem. Thanks to all, who read this thread and made their thoughts about it. * I found not any significant kernel messages regarding stale handles in syslog or dmesg. * The question about "noac"-mount-parameter brought me to check more mount options. The parameter lookupcache is quite signifcant. If I set it to "none", the problem disappears. while with the values "positive" or "all" the problem persits. - Though if I mount first with "none" and later with "all" the problem disappeared but only until reboot when it then was mounted with "all". - I checked this under openSUSE-12.2. - I made a quick check with openSUSE 11.4 whether "none" takes there also away the problem.
