20121113 Clearly reproducible on BcuNumber3 on LgswSystemSx

Description

After a "fresh" reset of the BCU the initialization goes smooth. A second initialization hangs the BCU, and a hard reset (red button on the BCU) may be needed. This was first noticed when a big number of subapertures were used as in subaperture set 20131112_182400 that contains XX subaps.

A workaround that sometimes work is to reconfigure the BCU with the "minimal" set: the BCU re-start and the next re-configuration with 20131112_182400 is OK.

Here follows the log of the controller when a re-configuration with subapertures 20131112_182400 is attempted:
