[leafnode-list] "last seen ... server now has ..." is the server's fault, right?

When I get a syslog message like this (it usually recurs for a few runs of 
fetchmail then stops):

Nov  1 22:31:26 garcia fetchnews[12579]: alt.religion.kibology: last seen 
article was 61692, server now has 61415-61690

does this indicate a fault on the remote server (from which fetchnews is 
downloading)?

Thanks,
Adam
