1. Daq crashes analysis

* tiInit problem - seems fixed, did not observe it during last 7 days; it made DAQ much more stable

* "Missing slots" - no new cases observed , still happens in run ending for dcrb's and vscm's, not a problem but will check it anyway

* clondb1 database access errors: run control reported error during query, mysql server on clondb1 reports 'unknown error' in error log, asked Marty Wise to investigate

* clonfs1 file server access errors: we have quite slow neaps so delays are expected; probably need to increase timeout waiting for clonfs1 in VTPs

* long wait on Go (30min for example) leads to 5% lifetime when run started, will investigate it during downtime

* VTPs: error messages implemented, GUI needed; message will be 'err:compname error_message', will discuss it more after the meeting

* helicity FADC board in adcecal4 slot 19 measuring helicity was replaced, broken one send to lab for repairs

* 3am log rotating problem was resolved by Nathan and Wesley, can help to decrease clonfs1 delays

2. DC road trigger development: last night data were taken to validate outbidding dictionary, currently running without dc roads but will turn it on after validation; gives about 15% reduction for electrons; dictionary can be cut on 1Gev for electrons which will give additional cut and decrease dictionary size allowing narrower roads, Ben will look at that

3. CTOF-CND trigger preparation: CTOF will be organized as 1-2, 2-3, 3-4 etc; cutoff-cnd will be discussed more (Nov 26 7GeV run starts, will need that trigger)
