failed: Stream is smaller than expected (0 < 5098)

Hi

Looks like I have got in a situation with missing or corrupted attachments. I am getting from time to time

lmtp(17147, user1@example.com): Error: read(attachments-connector(zlib(/var/spool/mail/example.com/user2/mail/storage/m.203))) failed: read(/srv/attachments/user2/4a/e0/4ae062027dd745f56c2cc1c43fa4f349f52986a0-2bcf4e063994235bfb4200006f28d014[base64:19 b/l]) failed: Stream is smaller than expected (0 < 5098)

Replication works, but is there a way to recover the logic even with empty files or cleaning indices? Thanks

Vladimir
