What is kmem_lp and should I care when it has a non-zero fail counter

Hi,

we have a rather busy M4000 (128G RAM, 4 CPUs a 8 Cores)  running Solaris 10 Generic_150400-23 (20 zones, mostly Oracle DBs) here and I noticed that some kma fail counters are non-zero:

root@xxx:/ # echo ::kmastat | mdb -k

cache                        buf    buf    buf      memory     alloc alloc

name                        size in use  total      in use   succeed  fail

------------------------- ------ ------ ------ ----------- --------- -----

...

sfmmu_tsb_lgrp1_cache       8192   1197   1457   11935744B 347485983 193876

...

Total [kmem_tsb_lgrp1]                           11935744B 347485983 193876

...

vmem                          memory      memory     memory     alloc alloc

name                          in use       total     import   succeed  fail
