Cisco Anyconnect Creating >100MB hosts.ac file

I had someone call me who was having problems with their Cisco Anyconnect Disconnecting regularly.  He is running Windows 7 and notices that the C:\Windows\System32\drivers\etc\hosts.ac file is growing to like 107MB in size.  I don't usually use Anyconnect but that sounded rather odd that a hosts file could grow that large.  Would that be considered normal behavior?  Thanks.  Any other thoughts on trouble shooting Anyconnect more generally?

it looks lik there is a problem with some Anyconnect client versions

A hosts file of that size is very questionable, they are typically well under even 1Mb...

How big is your ...\etc\hosts file? hosts.ac is just a copy of that file after anyconnect is installed,

I can't say how big the \etc\hosts file is because I was brought into the discussion as a favor to one of our Exec's friends.  One of those late evening calls out of the blue where someone's own IT department isn't getting it done so they start shaking the friend tree.  :-)  I reviewed how I would approach the problem and noted the 107MB hosts.ac sounded weird.  Never a dull moment.

If the hosts file is just as big as the host.ac then there may not be a problem. If the files are drastically different than I would delete the hosts.ac file (after making a copy) then reboot the box to see if anything changes. A new hosts.ac should be generated.
