I am just experiencing the following problem: I have a computer which is not connected to the internet all the time, so sometimes the BOINC client tries to contact the scheduler but cannot reach it. In this case the client terminates the running process and all preempted processes. This is especially obstructive when running climateprediction.net which has a large checkpointing interval, so it is interrupted all the time. Here is an example (first connection successful, second connection causes the termination):
