Ok, in that case we use it.
We don't think that is the cause right now, because we have had abends
in both z/VM systems within 5 minutes.
Maybee disk or network could be the cause, that's the two things
in common.

Not true. The cmm_pages is for CMM-1. There is no instrumentation for
CMMA in Linux. There's only a kernel parameters cmma= for which the
default varied per kernel (see pg 39 in my LX45 presentation).
If you don't want Linux to use it, your best bet is to disable it on
z/VM (system wide or per user).
