A race condition in the terminate handler of the icrd_child process causes it to crash and generate a core.


This does not impact functionality, but the system posts messages to icrd log similar to the following: notice icrd: 5823,14414, RestServer, INFO, Connection idle too long fd:11.


This is an intermittent issue that is caused by a race condition.



Fix Information

This release fixes an intermittent race condition in the terminate handler of the icrd_child process, so the process no longer crashes and generates a core.
