how far unclean shutdowns can corrupt MyISAM tables ?

[paul]

hello,


i have a solaris 9 server and mysql 4.1.14 64bit (was 4.1.7).
i've just discovered that we have most big tables that
need to be fixed or are corrupted. nothing in the logs.

the only probable cause i've found is that mysql wasn't
stopped at all at each reboot/shutdown.
at the time of the reboot, the base was running but not in use.

do you think +- 30 reboots in 10 months (without "mysql stop") could
lead to most tables being corrupted ? (20 Go of data total)


thanks, paul.
