This is a different bug, and I suspect it might be caused by virtual plugin. We'll look into it.

Ok!
So the subject for this bug is correct...
Do you need some configs and deeper descriptions from me?
I have two namespaces with virtual mailboxes:
The first "Real" is normally hidden. It's not hidden now for
debug-purpose.
namespace Real {
hidden = no
ignore_on_failure = yes
list = children
location =
virtual:/var/mail/real:INDEX=/var/lib/dovecot/db/indexes/real/%u
prefix = Real/
separator = /
subscriptions = no
}
namespace Synoptic {
hidden = no
ignore_on_failure = yes
list = children
location =
virtual:/var/mail/virtual:INDEX=/var/lib/dovecot/db/indexes/virtual/%u
mailbox INBOX/Archives {
auto = no
special_use = \Archive
}
mailbox INBOX/Drafts {
auto = no
special_use = \Drafts
}
mailbox INBOX/Entw?rfe {
auto = no
special_use = \Drafts
}
mailbox INBOX/Junk {
auto = no
special_use = \Junk
}
mailbox INBOX/Sent {
auto = no
special_use = \Sent
}
mailbox INBOX/Spam {
auto = no
special_use = \Junk
}
prefix = Synoptic/
separator = /
subscriptions = no
}
The "Real" namespace is to get a first filter for emails for all, the
last 1, 2 and 3 years:
Here is the virtual-mailbox-definition:
/var/mail/real: # tree

The error only appears in a Mailbox from one of this two namespaces.
Every other mailboxes (public, private, shared) are working correct.
When i try to open a mailbox from one of this two namespaces, the error
below (Panic: Leaked view for index) is throwen

Does it always happen with 2.2 and 2.3? I was not immediately able to reproduce your problem.

So the subject for this bug is (now) correct... I found out, that the count of mailboxes is not the problem. But the count of emails!! So i deletet all my mailboxes an created them new with doveadm. 430 empty mailboxes existed then. No problem with my virtual boxes. Then i restored my emails mailbox for mailbox from backup. After each restored mailbox i tested the virtual mailboxes. It worked with 15482 emails. Then i restored a larger one.? The total amount of emails was then 16843, and the virtual mailbox crashed like before. Then i deleted the emails from the box... all is working. I added them again, deletet 200, all is working. deleted all of them again and added them again... so they are again 16844 (one email arrived in another mailbox), all is working. :-/ Put more and more emails to my mailboxes... checking every time if virtual mailboxes are working, so i get a new error: J?n 05 14:28:18 aldebaran dovecot[17022]: imap(jakob)<5117><S0pzWAdiE/hcPAkS>: Panic: file mail-index.c: line 793 (mail_index_close): assertion failed: (index->open_count > 0) J?n 05 14:28:18 aldebaran dovecot[17022]: imap(jakob)<5117><S0pzWAdiE/hcPAkS>: Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0xc6021) [0x7f419fecd021] -> /usr/local/lib/dovecot/libdovecot.so.0(+0xc60ed) [0x7f419fecd0ed] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f419fe3f481] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0xf39a8) [0x7f41a026c9a8] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0xd92d1) [0x7f41a02522d1] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0xd9363) [0x7f41a0252363] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_mailbox_free+0x9) [0x7f41a0243f39] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(+0xd05a4) [0x7f41a02495a4] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_free+0x19) [0x7f41a01c3c99] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(+0xabdc) [0x7f419b42ebdc] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(+0xacb9) [0x7f419b42ecb9] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_close+0x1a) [0x7f41a01c3c0a] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(+0xac60) [0x7f419b42ec60] -> /usr/local/lib/dovecot/lib20_virtual_plugin.so(+0xacb9) [0x7f419b42ecb9] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_close+0x1a) [0x7f41a01c3c0a] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_free+0x13) [0x7f41a01c3c93] -> dovecot/imap [jakob 92.60.9.18 select](imap_client_close_mailbox+0x5b) [0x564c2088205b] -> dovecot/imap [jakob 92.60.9.18 select](+0x14f03) [0x564c20879f03] -> dovecot/imap [jakob 92.60.9.18 select](cmd_select_full+0xf9) [0x564c2087a129] -> dovecot/imap [jakob 92.60.9.18 select](command_exec+0x64) [0x564c20881ca4] -> dovecot/imap [jakob 92.60.9.18 select](+0x1b0b2) [0x564c208800b2] -> dovecot/imap [jakob 92.60.9.18 select](+0x1b13c) [0x564c2088013c] -> dovecot/imap [jakob 92.60.9.18 select](client_handle_input+0x1a5) [0x564c20880565] -> dovecot/imap [jakob 92.60.9.18 select](client_input+0x82) [0x564c20880be2] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7f419fee4c09] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x109) [0x7f419fee64a9] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x52) [0x7f419fee4d12] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f419fee4f28] J?n 05 14:28:18 aldebaran dovecot[17022]: imap(jakob)<5117><S0pzWAdiE/hcPAkS>: Fatal: master: service(imap): child 5117 killed with signal 6 (core not dumped) Do you need some configs and deeper descriptions from me?
