apt-get (status file) broken?

[Adahma <adahma@starport.org>]

I get the following error when trying to use apt-get or dselect:

Hit http://non-us.debian.org unstable/non-US/non-free Release
Reading Package Lists... Error!
E: Dynamic MMap ran out of room
E: Dynamic MMap ran out of room
E: Error occured while processing liblircclient0 (NewVersion1)
E: Problem with MergeList /var/lib/dpkg/status
E: The package lists or status file could not be parsed or opened.

I'm running Sid.  I have not seen any related list traffic on such
an error, so I'm guessing it's just my system, and a hosed file.
Can anyone give direction on how I might rectify such a problem?

Thanks!
