So, presumably you have configure Mailman to deliver archivable message by
command directly to MHonarc rather than having MHonarc get the material via
It is a pity you did not mention the use of MHonarc to start with. The
error message you quotedin your earlier post as being generated on
mailmanctl start is eerily similar to one described in a file I found in
MHonarc's distribution MHonArc2.5.13/doc/app-diagnos.html#warnings; I do
not use MHonarc myself but grepping through an expanded distribution found it.
Warning: Database (dbversion) != program (prgversion) version
Indicates that the version of MHonArc updating an archive is different from
the version of MHonArc that created the database file. Problems can arise
if the database file changes in format from different version of MHonArc.
See the release notes of the MHonArc distribution if changes in the databse
format will effect older archives.
It seems a reasonable speculation that you have updated MHonarc at some
point and this is the cause of the problem and possibly this problem has
nothing to do with Mailman but that MHonarc is grinding exceeding small? It
also explains why the problem appeared to followe Mailman. But maybe it is
following MHonarc which is attached to Mailman??
