Hello Janne, nice to not be alone ... We did some things during the last accident: - Changed the alive time of buffer to 3 seconds from 30 - Started the wakeup of the kupdate daemon every 0,6 seconds These both things are described in http://www-106.ibm.com/developerworks/library/l-fs8 (search for the work kupdate) We also changed from data=ordered to data=journal (seems to be better for database usage). We did not tested since the changes where made because some persons are working on the machine (and after working a few weekends in a line I got a little bit tired). Annother try worth in my eyes would be a bigger journal. Our current journal is 33 MB on a 40 and a 60 MB disk. If its a journal overflow may be 500 MB will solve the problem. As I understand from your mail it is not a kernel problem of kernel 2.4.10.
