ufs problem

[Evgenii Davidov]

dear fs-wizards
i have such a problem:
some groups of files get corrupted from time to time:
find: /usr/src/crypto/openssl/crypto/bf/asm: Bad file descriptor
find: /usr/src/crypto/openssl/crypto/bn/asm/alpha: Bad file descriptor
find: /usr/src/crypto/openssl/crypto/bn/asm/alpha.works: Bad file descriptor
thou they was not accessed even for reading last days
fsck says "partially allocated inode" and erases them
i have chaged the ide disk, and it's cable too, and plugged it in an other controller but it'd didn't help me
"make -j32 buildworld" works compleetly
disk activity is not high:
