Hi Scott, How does one know if the vfs.ufs.dirhash_maxmem is set too high and are exhausting KVA ? We set it quite high on our pop3/imap servers since Maildir can contain many small files. eg % sysctl -a vfs.ufs | grep -i dir vfs.ufs.dirhash_minsize: 2560 vfs.ufs.dirhash_maxmem: 99097152 vfs.ufs.dirhash_mem: 59259609 ---Mike >Scott >_______________________________________________ >freebsd-stable@freebsd.org mailing list >http://lists.freebsd.org/mailman/listinfo/freebsd-stable >To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
