ipac-ng chains or rules corrupted

[Christian Christmann <plfriko@yahoo.de>]

Hi,

after running my Debian box for couple of hours I get
every 5 minute a mail by cron with the content:

ipac-ng chains or rules corrupted, fix this with fetchipac -S

Running fetchipac -S I get the error message:

 calloc failed
: Cannot allocate memory


Any ideas what's wrong with ipac-ng and how to solve that
problem?

Regards
Christian
