When the rx buffer is too small for a packet, we will discard the vq descriptor and retry it for the next packet: while ((sock_len = vhost_net_rx_peek_head_len(net, sock->sk, &busyloop_intr))) { ... /* On overrun, truncate and discard */ if (unlikely(headcount > UIO_MAXIOV)) { iov_iter_init(&msg.msg_iter, READ, vq->iov, 1, 1); err = sock->ops->recvmsg(sock,

I setup new server with dovecot 2.1.12 and mboxes from backup (moboxes was used with dovecot 1.1.6). OS: FreeBSD 8.3-STABLE, amd64. All index files from dovecot 1.1.6 has been deleted. Some times dovecot processes aborted. E. g. Jan 25 03:01:52 ost dovecot: lda(user at example.ru): Panic: file mail-transaction-log-file.c: line 1694 (mail_transaction_log_file_map): assertion failed:

We upgraded from Dovecot 1.0.15 to 1.2.5 last night, on Solaris 10 using mboxes, mostly without issues. However I had to trash the index/cache files (too many folders were showing corruption issues which is especially bad for Prayer Webmail ".prayer" folders that store preferences; Prayer sees a disconnection as the folder being missing!). I've had one imap process panic in mailbox
