RETURN VALUE
On success, the PID of the child process is returned in the parent, and
0 is returned in the child. On failure, -1 is returned in the parent,
no child process is created, and errno is set appropriately.

.....
ENOMEM
fork() failed to allocate the necessary kernel structures because
memory is tight.

CONFORMING TO SVr4, 4.3BSD, POSIX.1-2001.

So it does not necessarily mean that claws is leaking memory. It could
also be because other processes running on your system has taken all
available memory.

Try use top to see what is using memory.
