Problems with apt

["David A. Cobb" <superbiskit@cox.net>]

After using it successfully several times a week, every run of apt-get
or aptitude now ends with:

E: Dynamic MMap ran out of room
E: Error occurred while processing python2.3 (NewVersion2)
E: Problem with MergeList
/var/lib/apt/lists/mail.linuxvar.it_%7egianluca_athlon-xp_dists_sarge_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

The specific /var/lib/apt/lists file that show up as MergeList varies
depending on how many active
sources I hav in sources.list

I'm guessing this is more likely a configuration problem than an apt bug.
Can anyone give me a clue?

TIA
