Looks like some kind of data corruption for the internal
state database that would prevent Apache::ASP from cleaning
up the state files correctly. Do you have the StateDir shared between
hosts on some network file system? This could cause corruption.
Failing that, you may have uncovered a scalability issue
with SDBM_File which is used for the internal state dbm always
for speed.
If you want to change the type of dbm used for the internal
database, you can do this:
PerlModule Apache::ASP
<Perl>
$Apache::ASP::DefaultStateDB = 'DB_File';
</Perl>
StateDB only works on $Application & $Session, but not
the internal database, so I believe the above will work.
I could also add some code that could work around the
data corruption issue you are facing, and we can try
that if you like.
