Error: spawn E2BIG

Hi!

A service running many days begins to log this error.

Error: spawn E2BIG

The line mentioned in log is
var child = childprocess.spawn(this.options.phantomPath, [].concat(this.options.phantomArgs, [this.script]), this.options.childProcessOptions)

In my local environment printed the content of this.options.phantomArgs, which is an array, bigger and bigger in each execution. For example

First execution:
[ '--local-url-access=false' ]

Second execution:
[ '--local-url-access=false', '--local-url-access=false' ]

Third execution:
[
'--local-url-access=false',
'--local-url-access=false',
'--local-url-access=false'
]

and so on until reach the supported max command length, throwing E2BIG exception.

Thanks in advanced.
