Spmi: Common Memory locked by process

Easily seen as:

ksh$ topas
topas: Unable to initialize Spmi interface
Spmi: Common Memory locked by process 69904, requestor: 90692 (SiInit)

Some process using the Spmi API (System Performance Measuring Interface) has not released a lock correctly. This will prevent saposcol from starting, amongst others. If this is on an SP node running PSSP, try restarting haemaixos:

ksh# stopsrc -s haemaixos
ksh# startsrc -s haemaixos

This doesn't appear to impact the normal running of the system, and has addressed the issue in our case.
