As posted in another thread, here two log snippets that show the freeze (guide cam timeout):
At 23:25:58 the guide graph got stuck for the first time. The logfile reports:

Another freeze happened later during the same night:

no entry for 26s! The guide graph did not update (as no further guide images were received). This time I did not interrupt but waited for what happens. Once the 300s image from the main cam had downloaded, dithering and guiding resumed normally but the image received from the main cam had a HFR of 1.9 which indicates that guiding did not work during these 26s.
