today I was testing the ENVnoise server, injecting white noise to CEB_DACroom, while I noticed reappearing the "bad-coherence problem" between in and out signals, the problem reappeared between 9:42 UTC and 9:50 UTC and it is still there: Figure 1 shows 9:42 UTC (good coherence) and Figure 2 shows 9:5o UTC (bad coherence).

I wander if this might be related to the work on DAQ servers performed this morning, In particular channel CEB_DACroom belongs to DaqBox 24 which is configured in Acl process SIB2_SBE. I report here the extract from VPM log file during this period:
