The mailbox which fails is quite large (over 32000 msgs and over 1GB). 
mbexamine produces a very large output for all mails. I can see that it 
doesn't fail: it terminates without errors and with 0 exit status.

Even switches -c or -q terminates without errors. All quotas checks are 
correct.

I understand. As soon as I can, I'll setup a normal replica.

Thank you
