error messages from easyraid ex array are there again

[Fritz Heinrichmeyer]

Hello,

in march 2005 i reported strange scsi error messages from ahc driver and 
an easyraid ex system, i have not seen this messages for some month now 
(could also result from the fact that cyrus imap server was less used 
..). It raises on a partition where some files containing berkeley-db 
4.x databases are located that are massaged by cyrus imap server. I 
suspect there is no real media error, as nothing is announced at the 
control panel. Now i use freebsd 6 stable (compiled last week, SMP with 
two xeon CPUs).

There where no such messages under the FreeBSD 4.x versions.
