It is called FAM for a reason. FAM == File Alteration Monitor

If you are currently modifying or have some files open, it makes sure
that the processes that have them open are notified that another process
(should you open a file with something else) has opened them. If you
change these files the other processes are are notified and given a
single to "do what they do" in this case. If they don't care... then FAM
has done its job. If they do care... then FAM has done its job.

It is things like Trash, IMAP servers, WebDAV servers and clients to
notify you "HEY, blargenfingle file changed as we have it open. Do you
want to reload it or blah.blah.blah this fizzering?"

This is an important feature, the reason FAM was taking a bit of CPU
time, it was monitoring the actions the other programs were taking on
the files you had open. Given that you were dealing with a webdav
server, probably lotsa files were open.

If you are not actually running any servers or have other people on your
machine, you should be able to survive without it. But remember you
might have probs, or you might not. Depends on what you are doing.
