For others who might want help with this, tweaking
vfs.ufs.dirhash_maxmem is what is needed. A bit of a balancing act is

also tweak KVA_PAGES.
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
