    Description

      I see the following message on the console of one of our Sequoia login nodes:

      2013-02-12 15:26:17 Lustre: ldlm_cbd: This service may have more threads (192) than the given soft limit (128)

      Is this troubling? What's the net effect of this?

          I'm more inclined to just quiet the message entirely, i.e. CDEBUG(), since there isn't anything the sysadmin can or should do about it.

          I guess at some point we need to look at whether there should be one set of threads running on each of the cores, or if one set of threads per socket is enough?
