I would suggest it is hardware or OS related. Have you checked the OS error messages (/usr/adm/messages) to ensure there isn't a disk related problem? Is it only the /opt filesystem that shows these problems? If other filesystems have the same errors, are they on the same physical disks?

The first thing I would suggest you do is unmount the opt filesystem and run fsck on it manually. When the system is booted, it will only run fsck on the filesystem if it is marked "dirty".
