Yes the engine was brought up by a cold restore (ontape -r). Ontape is
only a manager of the restore process the oninits do all the work so
after restoring the reserved pages itself ontape starts up the Informix
engine to do the rest. The undocumented -r argument to oninit notifies
the master oninit process to coordinate with the ontape and not attempt
to read anything beyond the reserved pages (the DATABASE TABLESPACE and
TABLESPACE TABLESPACE are normally read at startup but they are not
there). When the restore completes the engine is in quiescent mode and
apparently someone ran an onmode -m to bring it online. When you next
shutdown and restart that instance the "problem" will vanish.
