Statmonitor data does not include system stats for linked topaz with s-bit set
System statistics may not be collected for linked topaz sessions, if topaz
is started as a user other than the user owning the GemStone processes,
the users are not in the same group, and the s-bit is set for the topaz
executable. This is since the /proc/<pid> files that contain the system
stats information are owned by the userId that starts topaz. If the userId
that started statmonitor does not have permission to access these files,
no system statistics are available.
Running statmonitor as root will allow it to access the files.
