VM UMA counters.

[Santiago Martinez]

Hi there, sorry to ask this as it might be a silly question...

Since a few weeks im seeing random locks on application and sometimes
when using truss it show resource temporally unavailable.

Now, checking random things, i see that the
vm.uma.256_Bucket.stats.fails counter is increasing while the other are
not (at least for now).

Here goes the output:

vm.uma.256_Bucket.stats.xdomain: 0
vm.uma.256_Bucket.stats.fails: 762142
vm.uma.256_Bucket.stats.frees: 41935
vm.uma.256_Bucket.stats.allocs: 42721
vm.uma.256_Bucket.stats.current: 786

My question is, is this the expected behavior?

Regards.
