Build Identifier: 

In this patch, it mainly fixed 3 kind of issues:

1. Fixed one signal handling issues: The old sigmask needs to be restored if the pthread_create failed.

2. The notification array "serialTest[serialNum]" needs to be set to the initial data when doing the allocate. Otherwise, when the data would be incorrect when the array is reused after multiple times.

3. Add codes to catch certain memory allocation exceptions

4. Add correct error check, and return the errcode back when the "feAgent->syncWait()" got an error or the connection handler failed.

Reproducible: Always
