| ERROR | OS error string creating shared memory segment of string bytes with key string |
| CAUSE | The shared memory segment could not be created as requested. For example, a segment with the provided key may already exist, or the size may be outside of system allowed range. |
| ACTION | Use the error code to determine the exact cause of the problem. In certain cases the problem may be resolved by adjusting the system-imposed limits such as the maximum number of allowed shared memory segments, or their maximum and minimum sizes. In other cases, resources need to be freed up first for the operation to succeed. |
