Hi Philip, Thanks a lot for the explanation. In deed, these error messages rarely appears. My current script just logged their presence and thus is not able to tell which probe is responsible for them at what moment. If the case is of interest to you, I can look into it later. Again, many thanks. Regards, wenqin

Hi,
Could someone please help me figure out what these error messages in result field of ping measurement mean? - error: sendto failed: Invalid argument (related to name resolve?) - error: sendto failed: Bad file descriptor
These are errors returned by the sendto system call on the probe.
The sendto(2) manual page on Linux gives a description of when sendto returns those errors.
By and large I would say that these errors are not supposed to happen. So this is probably a bug in the probe code.
