Could not spawn trampoline???

Hello!

In my company we are running automated tests on iPads and iPhones.

The first step in each test is to install the device with our app. We use ios-deploy (https://github.com/phonegap/ios-deploy) for that.

However, after some 10-40 runs of such cycles, the device seem to be stuck, forcing us to manually reboot them. The logs show these lines:

Feb  8 17:34:39 ve-ios-02 kernel[0] <Notice>: proc: table is full
Feb  8 17:34:39 ve-ios-02 com.apple.xpc.launchd[1] (lockdown.735108597492.com.apple.springboardservices) <Error>: Could not spawn trampoline: 35: Resource temporarily unavailable

Any idea for how to solve such problems?

Thanks!
