Miyoki-san found that some vacuum readouts showed too large value in short time.

According to my investigation, CC-10 sometimes returned strange format to the command reading the pressure value. In the cases of the access error from k1script to each RaspPi, the access error from RaspPi to CC-10, and the error code coming back from CC-10, DAQ records negative value. But in this issue, CC-10 returns a wrong value which cannot be distinguished from a correct value.

I haven't identified the cause of this issue but I found the response of some RaspPi which sometimes returned a strange value was too slow. These RaspPi fell in the same problem as klog#32514. So I restarted GUI process on these RaspPi.

For current implementation, same problem will be reproduced (probably in several weeks later?). To-Do list for mitigating this issue is as follows.
- More strict check of the return value from CC-10 will be implemented (for better trouble detection).
- Run level of RaspPi will be changed from graphical.target to multi-user.target (for removing a cause of trouble).
- NTP daemon will be installed to RaspPi (for better log investigation; now system time is off by an order of years).
