dovecot: imap-login: Panic: Trying to allocate 0 bytes
by Ron Garret 08 Mar '16

My ISP had a hard drive crash. After the dust settled, my dovecot installation started failing with the following error every time a client tries to connect: dovecot: imap-login: Panic: Trying to allocate 0 bytes My installation has otherwise been stable and rock-solid for years. Both I and the techs at my ISP are stumped. Any advice on how to debug this would be greatly appreciated.

[PATCH] imapc: Accept strings in FLAGS responses
by Richard Laager 08 Mar '16

08 Mar '16

While non-standard, the IMAP server we are replacing returns non-system flags as strings instead of atoms.

segfault in imap and doveadm
by Joe Beaubien 07 Mar '16

07 Mar '16

Hi everyone, Dovecot keeps on segfaulting on me and I am unsure why. This setup has been running for 5 years and has given me very little trouble. I am running Dovecot 2.1.7, setup with mdbox. The imap process keeps on segfaulting for the same account (makes me think maybe an email or folder of that account is problematic). My big issue is that force-resync also causes doveadm to segfault. Here is the mail.err file I am getting: Mar 7 12:34:36 mba kernel: [ 1955.486324] imap[5663]: segfault at 0 ip 00007ff1c1bd0b5e sp 00007fffd8599a40 error 4 in libdovecot-storage.so.0.0.0[7ff1c1b51000+fb000] Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Sara/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:37 mba dovecot: imap(document): Error: mdbox map /mba_data/emails/document/storage/dovecot.map.index corrupted: map_uid=284393 refcount too low Mar 7 12:34:37 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:39 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:42 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/_EE - a verifier/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:43 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:48 mba kernel: [ 1967.972883] imap[5688]: segfault at 0 ip 00007f058ebc9b5e sp 00007fff9baa7c00 error 4 in libdovecot-storage.so.0.0.0[7f058eb4a000+fb000] Mar 7 12:34:49 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:43:44 mba dovecot: imap(document): Error: indexer disconnected unexpectedly Mar 7 12:43:44 mba dovecot: indexer: Error: Indexer worker disconnected, discarding 119 requests for document Mar 7 12:48:31 mba kernel: [ 2790.363755] doveadm[6586]: segfault at 0 ip 00007f1b2023fb5e sp 00007fff4e8ce200 error 4 in libdovecot-storage.so.0.0.0[7f1b201c0000+fb000] Mar 7 12:49:10 mba kernel: [ 2829.203900] doveadm[6604]: segfault at 0 ip 00007fa0d16e4b5e sp 00007fff1b89f480 error 4 in libdovecot-storage.so.0.0.0[7fa0d1665000+fb000] First line is imap segfaulting.

Compilation fails: SSL_TXT_SSLV2 not defined

Hello all, I'm trying to compile dovecot 2.2.21 on OS-X 10.11.3 and I'm running a bit of trouble with OpenSSL.

questions regarding zlib plugin
by Götz Reinicke - IT Koordinator 07 Mar '16

07 Mar '16

Hi, faced with a current space problem on our dovecot 2.2.18 server, I thought about using the zlib plugin. My questions: - is it really as simple as adding the options to the conf files as described in the docs :) ? http://wiki2.dovecot.org/Plugins/Zlib - As this just compresses new messages; dose anybody has a sort of simple cron or whatever script or best practice how to compress existing maildir mails? The doc is a bit complicated to me at that point... Thanks a lot and regards . Götz

Since dovecot put up packages on their own repo, bigmichi stopped providing his'. I guess this is not Stephan; Would the kind person update ppa.launchpad.net/bigmichi1 ? Thank You -- peter

I guess something like /etc/sudoers for API keys would be good? Did I miss something? -- peter
