4 Nov 2009 F. Py 2009.308.04 2009.308.07 25197s 6h 59m 57s TRUE      
5 Nov 2009 T. Maughan 2009.309.00 2009.309.01 2043s 0 34m 3s FALSE Model ascend longer than expected over constrained model of the ascend in TREX.  - a patch was applied on other branches but not in the volume survey deployed for this run.   
5 Nov 2009 T. Maughan 2009.309.01 2009.309.06 2064s 0h 34m 24s FALSE Model ascend longer than expected    
5 Nov 2009 T. Maughan 2009.309.02 2009.309.07 1016s 0h 16m 56s FALSE Interface vcsServer socket closed VcsServer:   in analyzing the failure it was determined by Frederic and Hans that the implementation was overly complicated and could be simplified to improve maintainability and reliability.  
5 Nov 2009 T. Maughan 2009.309.03 2009.309.07 1012s 0h 16m 52s FALSE Interface vcsServer socket closed    
9 Nov 2009 F. Py 2009.313.02 2009.313.04 19026s 5h 17m 6s FALSE AUV MVC altitude stop: it was believed that sea conditions caused the dvl to malfunction as the ping temporal spacing caused it to hear echos and deliver a wrong altitude.   No way for TREX to recover from navigation instrument failure. Altitude: Hans changed the frequency of the signal beams to avoid the false altitude.   He also patched another issue in the driver.  
10 Nov 2009 T. Maughan X 2009.314.01 0s 0 FALSE Failed to execute Navigation (crash) Navigation crash:   All components of mvc needed to be compiled with a specific flag.    After two tries, we drove the boat back and applied the rebuilt code.  
10 Nov 2009 T. Maughan X 2009.314.03 0s 0 FALSE Failed to execute Navigation (crash)    
10 Nov 2009 T. Maughan X 2009.314.05 7029s 1h 57m 9s FALSE mvc-dmo1 crash MVC-DMO1 crash:   it was determined that a patch should be applied to QNX, Hans patched the QNX on the vehicle and the test machines.  
18 Nov 2009 T. Maughan 2009.322.07 2009.322.09 577s 0h 9m 37s FALSE parosci + ahrs issues Post deployment analysis showed significant differences between the DMO mvc qnx code and the autonomy branch of the mvc qnx code.  
18 Nov 2009 T. Maughan 2009.322.09 2009.322.10 10398s 2h 53m 18s TRUE AUV issue: Tailcone locked resulting in the abort from TREX.   Also, bad weather motivated the attempt at early termination. Tailcone issue was found to be loose screws on one of the actuators.    Also, the error recovery was analyzed on the TREX side and the tailcone failure revealed a dispatchability issue at TREX level which is now corrected by avoiding to dispatch a behavior before it can start (to be refined but OK)  
19 Nov 2009 F. Py 2009.323.01 2009.323.02 4274s 1h 11m 14s FALSE parosci error This error was related to the code diffs in the autonomy branch of mvc code  
19 Nov 2009 F. Py 2009.323.02 2009.323.06 2094s 0h 34m 54s FALSE parosci error "  
8 Dec 2009 F. Py 2009.342.04 2009.342.05 9359s 2h 35m 59s TRUE altitude stop: (see Nov. 9).   Gulpers:  it appears that the gulper commands were potentially too closely spaced for the driver. This error was related to  the fact that our branch was not up to date and specifically did not include latest updates related to AUV HW modifications
