> I didn't changed anything from the defaults... it looks like that: > mhettwer@submaster-test$ sysctl vfs.ufs.dirhash_maxmem > vfs.ufs.dirhash_maxmem: 2097152 > mhettwer@submaster-test$ sysctl vfs.ufs.dirhash_mem > vfs.ufs.dirhash_mem: 368622 You could try the following change: sysctl vfs.ufs.dirhash_maxmem=3D8388608 Did you use the GENERIC-kernel? If so, remember that witness, invariants etc. are a part of the RELENG_6-branch. You should disable these settings with a custom-build kernel. You may also want to read /usr/src/UPDATING. regards Claus
