This is a different bug, and I suspect it might be caused by virtual

Ok!
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:

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/Entwürfe {
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:

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

Hi!
This is very strange...
This error affects only one mailaccount, and it happend not yesterday.
The file
/var/lib/dovecot/db/indexes/Maildir/jakob/INBOX/dovecot.index
which hat "Panic: Leaked view for index" does not exist. only
dovecot.index.log and .cache exists in this mailbox. (which is normal
for small mailboxes, i've read). But why is dovecot throwing an error?
And i could find out, this is only, when i try to open a virtual folder.
I switched back to older self-compiled dovecot-versions... but the error
exists also there (but not before the update!!!)
I also deleted all the dovecot.index-files, dovecot.index.log and
dovecot.index.cache-files to let rebuild dovecot the index again... the
error persists.
Is it a misconfiguration?
So i tried to build for the virtual-Mailboxes the Index in memory... the
error persists and dovecot wants to read this index-file.
My virtual folders not working any longer (on this account only!)
For debug purpose i deleted all the emails in this mailbox, the error
dissapered on this folder, but comes back in the next folder.
could this be a problem with ulimit?

Hi!
Is this a bug according to the other one?
When i try to open a real or virtual mailbox, i often (not on every
