[Mailman-Users] [URGENT][SUBSCRIBERS VANISHED, No entries in LOG]

[Ganeshh]

Dear Lists

I am running 30 lists on mailman 2.0.8 and out of which 20 to 25 of them 
are really active. The mailing system is working fine , but i like to 
share with
you a strange behaviour with mailman, or maybe i dunno it could an human 
error.

I added my 31st list on 23rd January and please find the below log, as 
it routine exercise of creating lists and mass subscribing the members, 
i didnt check the list members status on a daily level. To my surprise 
of out 9 members subscribed, only 3 of them exist.

My subscribe log was not modified by anyone or tampered, and i dont find 
any logs of members who arent existing anymore with stamp "deleted"

What could be cause of this problem...

Thanks in Advance
