Problem

When invoking fbsvcmgr with operations requiring the USE_GFIX_UTILITY system privilege, the utility exited silently — no error was printed to stdout or stderr.

Root cause: a timing issue introduced by the started() call left insufficient time for the error response to be received and displayed before the process exited.

Before / After

Before:

$ ./fbsvcmgr localhost:service_mgr -user user1 -password user1 -action_properties -dbname employee prp_page_buffers 4096

After:

$ ./fbsvcmgr localhost:service_mgr -user user1 -password user1 -action_properties -dbname employee prp_page_buffers 4096
Unable to perform operation
-System privilege USE_GFIX_UTILITY is missing

Fix

Resolved a race condition between the started() call and the service response. Error messages are now correctly delivered and printed before the utility exits.
