One of the possible reasons is that you have requested too many backups of the host. In this case, the estimate request or the reply may not fit in a UDP packet. This will cause Amanda not to perform some of the backups. Fixing this problem involves modifying the way estimate requests are issued, so that no packet exceeds the maximum packet size, and issuing additional requests that did not fit in a UDP packet after a reply for the previous set is obtained. The probability of getting this problem has been considerably reduced since we increased the maximum UDP packet size from 1Kb to 64Kb, but some operating systems may not support such large packets.
One possible work-around is to try to shorten the pathnames of the directories and the exclude file names, so that more requests fit in the UDP packet. You may create short-named links in some directory closer to the root (/) so as to reduce the length of names. I.e., instead of backing up /usr/home/foo and /usr/home/bar, create the following links:
/.foo -> /usr/home/foo /.bar -> /usr/home/bar
then list /.foo and /.bar in the disklist.
Another approach is to group sub-directories in backup sets, instead of backing up them all separately. For example, create /usr/home/.bkp1 and move `foo' and `bar' into it, then create links so that the original pathnames remain functional. Then, list /usr/home/.bkp1 in the disklist. You may create as many `.bkpN' directories as you need.
A simpler approach, that may work for you, is to backup only a subset of the subdirectories of a filesystem separately. The others can be backed up together with the root of the filesystem, using an exclude list that prevents duplicate backups.

If this error appears only with local dumps (backing up server itself) or with Samba shares, the reason might be that your client on the server is not working properly.
The first thing to check is whether the inetd is configured correctly to run the AMANDA client.
My inetd.conf on FreeBSD contains:
amanda dgram udp wait operator /usr/local/libexec/amanda/amandad amandad amandaidx stream tcp nowait operator /usr/local/libexec/amanda/amindexd amindexd amidxtape stream tcp nowait operator /usr/local/libexec/amanda/amidxtaped amidxtaped
But refer to manual and documentation for detailed information about inetd and amanda.
Note: The other FOM-entries (wrapper-stuff) are yet to be discussed. See FOM
