Not all data is logged properly, empty logs generated, can't switch off CURRENT logging from command line

[GoogleCodeExporter]

What steps will reproduce the problem?
No special steps, just turning on logging.

What is the expected output? What do you see instead?
Some of the values(e.g. Pitch IN is consitently set to zero).
Empty log files are generated everytime the logs are cleared and the APM is 
rebooted

What version of the product are you using? On what operating system?
APM1 with Arducopter 2.3

Please provide any additional information below.
Please see some of the sample logs in the attachement

I confirm data logging anomalies. in 2.3 APM2, MP 1.1.31
Pitch IN only displaying 0.
Roll IN displays something weird, definitly wrong.
Sonar and Baro erratic readings, e.g. negative sonar values.

"The problem is that when dumping the log, there is too much (2 bytes exactly) 
read from the CTUN entry. You can see this in the log files, all lines for CTUN 
end with -17757. This can cause the state machine to get out of sync. You 
notice a sync loss happened when you see a line in the log with a single period 
"." in it."

Ok I will check for the "."

On the empty logs download issue:
*From MP when I enter "Log Download", the APM reports a certain number of 
logs(e.g. 6) numbered say from 39 to 45
*When I click download all logs, the MP dowloads empty logs 1-38

I'm not sure if this is an issue or a feature but thought I'd let you know. If 
I need to open another issue item to report this please let me know

We've found a few differences in the column headers in the mission planner.  We 
will update them shortly.
