It should be EAGAIN, per POSIX 1003.1-1996 section 3.1.1.4:
3.1.1.4 Errors
If any of the following conditions occur, the fork() shall return -1 and set errno to the corresponding value:
[EAGAIN] The system lacked the necessary resources to create another process, or the system-imposed limit on the total number of processes under execution by a single user would be exceeded.
For each of the following conditions, if the condition is detected, the fork() shall return -1 and set errno to the corresponding value:
[ENOMEM] The process requires more space than the system is able to supply.
