ws1 is unable to read and write on some EPICS channels while I can see these channels in fb4 or acromag1. These channels are:

• C3:PSL-NCAV_FSS_SLOWOUT
• C3:PSL-SCAV_FSS_SLOWOUT
• C3:PSL-NCAV_FSS_FASTMON
• C3:PSL-SCAV_FSS_FASTMON
• C3:PSL-PRECAV_BEATNOTE_FREQ
• C3:PSL-HEATER_SHIELD_DIFF_POUT
• C3:PSL-PLL_AUTOLOCKER_BEATNOTE_FREQ
• C3:PSL-PRECAV_BEATNOTE_FREQ_SIGN
• All C3:PSL-VCTMPSNS_x where x is 0,1,2 and 3
• Maybe more

I'm not sure what is causing this. I have rebooted cromag1 several times but this problem persists. Interestingly, there are a lot of channels which are getting updated on medm screens so the origin of the problem is probably localized to a single .db file. But everything looks fine to me, at least after first few debugging trials.

Well, because of this, it is impossible almost impossible to even manually tune the beatnote frequency to the required point. I'll first fix this because it seems like an error which shouldn't be ignored. Suggestions are welcome as I am new to EPICS-Modbus-upstart-docker things and might be missing something silly.
