An error message similar to the following might be logged at rare intervals while the BIG-IP system is operating normally: warning chmand[7018]: 012a0004:4: getLopReg exception: No LopCmd reply match found for action=0x1 obj_id=0x67 subobj=0x0 slot=0xff. This message might be followed by a log message similar to one of the following: err chmand[7018]: 012a0003:3: GET_MEDIA failure (status=0xffffffff) page=0x%1 reg=0x0. err chmand[32142]: 012a0003:3: GET_STAT failure (status=0xffffffff) page=0x%20 reg=0x50. This message might be followed by a log message similar to the following: warning chmand[5847]: 012a0004:4: getLopReg: lop data size does not match, u16DataLen=0x5 expected=0x7.
This problem might occur if the response to a request to read the status of the hardware registers for the management interface is delayed beyond the normally-expected timeout value. When this problem occurs, status of the management interface might be reported incorrectly, which might cause the management interface to flap momentarily. In this scenario, subsequent requests typically complete successfully, at which point status of the management interface is again reported normally, and expected functionality restored.
This problem might occur rarely on the BIG-IP 2000-/4000-series, 5000-/7000-series, and 10000-/12000-series appliances, and on VIPRION 2100, 2150, and 2250 blades.
