Weblogic.security.Encrypt -and- Not enough space

Question

This post has two questions.
I have a simple application on wls9.2 that is a web front end to the weblogic.security.Encrypt command line utility. It seems to work fine, but after a little bit of use I am seeing the following:
java.io.IOException: Not enough space

1) Here is the forking code:
try {
proc = Runtime.getRuntime().exec("java -Dweblogic.RootDirectory="+rootDir+" weblogic.security.Encrypt "+password);
BufferedReader bf=new BufferedReader(new InputStreamReader(proc.getInputStream()));
line=bf.readLine();
bf.close();
} catch (IOException e) {
Is there a better way to do this, without forking? Seems odd to execute a java call, in java, just to get the encrypted string. I'd like to call weblogic.security.Encrypt inline, but have been unable to do so.
2) Why would the Not enough space error creep up? Researching it, it seems like it is a swap problem, but that does not seem to be the case on our system. A top shows:
Memory: 8192M phys mem, 2769M free mem, 5004M swap, 5004M free swap
at the time of failure. Disk usage is looking great as well. The JVM heapsize is around 80% free. An lsof on the system shows about 150 open files on the managed server.
Any ideas on how to troubleshoot this would be appreciated.
Thanks

I use CCleaner from the AppStore to delete the 'useless' stuff. It's free and works great for me
