NCM capture fails with unknown error and when further examining the NCMSERV.OUT file you can see java.lang.ArrayIndexOutOfBoundsException everytime a capture fails. Once the Out of Bounds Exception happens for a device it is not possible to capture from this device anymore.
Handled the wrong differences indices coming from new algorithm to avoid accessing the out of bound elements in config strings.
Please open a support case and request patch
