When there is an error with communication between chmand and lopd, a message is logged giving information about the problem. That message is missing data useful to F5 for determining the cause of the communications error. Messages similar to: Jul 11 11:10:19 localhost warning chmand[7815]: 012a0004:4: getLopReg: lop response data does not match request, u16DataLen=0xb expected=0xb, u8Length=0x8 expected=0x, u8Page=0x28 expected=0x$, u8Register=0x50 expected=0xP The expected data values are missing in this message, making it more difficult for F5 engineers to determine what caused the original communications problem.


Added difficulty for F5 to determine what problem caused the error message to be logged.


This issue only occurs when there is some problem with the communication channel between chmand and lopd.



Fix Information

The expected data values are properly printed in the log message.
