Reopened.
Problem in the attribute validity check when creating and modifying log stream
IMM objects. This may cause log to crash instead of returning an appropriate
error message in some cases if attributes are set in an incorrect way when
creating or modifying IMM objects for streams. The current fix for #771
handles one of the problems but there is more to fix.

The issue is seen on cs 4871 with patches #688, #711 and #721. After we have
observed the issue we ran the same app on cs 4733 and we observed the same
issue.
The backtrace of the crash is as follows:
Program terminated with signal 11, Segmentation fault.
