In this case, the shell is using a pthread key, so it should be configuring an extra POSIX_KEY. The mentioned approach can fix the problem because it simply configures all objects without limits. A better solution is to understand how many of each kind of kernel object your application needs and to configure exactly that, so as to reduce the resource overhead. Note, though, that the unified work area means the C program heap and the kernel objects reside in the same memory, so that there is no set-aside for kernel space, so the configure unlimited is less problematic in this situation. But, you could have an allocation failure eventually.
