 **General Issues** **General Issues**
- + internet connection issue was quite a big headache throughout all experiments ​for YgBrett is on it.
-    ​Need to fill out the meeting roster +
-    * New machine in AuScope room +
-      * replacement ​for ops4 - half setup currently, no ERCOps4 is no longer. +
-      * New display machine with times etc. +
-    * Hobart 26m 70k stage getting too warm despite cryogenics and vacuum pressure parameters being optimal (AOV036 and AUA053) +
-      * Supply pressure has been topped up - may be related to this +
-      * Keep and eye on it +
-    * New little script thing - '​logit'​ - can run logit in ke or yg pcfs machine and it will cut out some of the junk (especially at ke) +
-      * can be run via ssh from ops8. +
-      * there may be a way to do this through the field system software itself. Jamie is looking into it.  +
-    * First test of the FLEXBUFF at Yg has happened, appears to be working OK. Need to determine a way to record to both mk5 and flexbuff. +
-      * Negative tsys values at Ke, currently have no cause identified. The issues with tsys values at Yg are related to the same DBBC communication issue responsible for the TPI overflow error.+
  
  
 **Handover Issues** **Handover Issues**
  
-  * R1900 +  * R4902: 
-    * TPI overflow again with fivept at Yarragadee (Patrick) +   ​ 
-      Jamie is trying to track down the cause of this issue appears to be an intermittent comms errorHopefully answer soon+   ​Yarragadee 12m:Autocorrelation spectra does not look like an r4 spectra.tried resetting the dbbc, didn't help. Jamie will look into it. 
-  * R4899 +   
-    Error “ probably ​no such disk” when running ​checkmk5 on the new disk at Yg (Tiege) +   
-      * mk5=get_stats?​ pings each of 8 drives in the disk packPerhaps caused by disk packs with only 4 hard drives instead of 8+  ​ 
-    * I edited the alarm config file for the log monitor to beep for this error as wiki said it was safe to ignore (Tiege) +  * R1903: 
- +    
 +   *Yarragadee 12m:- ERROR un 111 Connection refused; ERROR s5 -23 rfpcn: error opening, rfpic probably ​not running. ​Fixed with restarting Rxmon
 +    ​ 
 +  
 +  ​CRF112: 
 +    
 +   ​*Hobart 26m:- error - can't record while other data transfers. Had to reboot mk5. This was because of running external commands ​to halt the schedule. Note for the observer:- Windserver at hobart is reliable. Don't run external halt commands if windstow.sh is running.
  
  
 +  * T2133:
 +   
 +   ​*Yarragadee 12m:- DBBC delay jumped. Clocks are stable (-0.311 ns offset) and fmset is returning sensible values, but dbbc=pps_delay returns ~810168373. running fmset, and pps_sync, reconfiguring,​ rebooting didn't worked. reconfiguring again??? pci card is now replaced , that seems to solve this particular problem. ​
