Firstly, 2.2.13 is about 5 years old. So there's that. It would be helpful if you can reproduce this with 2.2.36.
Also, you forgot to actually include in your log snippet the panic. So maybe few more lines before the Raw backtrace?

Hi I have "problem" with dovect 2.2.13 from repo debian8 and I don't know how to solve it ...
Server is a virtual (kvm) with debian 8.11 (postfix + dovecot from repo) and storage is mounting via nfs (I have use only one dovecot with external storage)
All works fine but sometime ( after a few hours ) I have got a problem with dovecot cache (i use indexes) logs -> http://paste.debian.net/1117072/
The store is mounted via nfs in /home/ index is local in /var/dovecot_indexes%h
All go back to normal when i remove indexes like: find /var/dovecot_indexes/home/ -name 'dovecot*' -type f -delete but this is not good solution
What am I doing wrong ?
For tunning nfs in 10-mail.conf:
"mail_location = maildir:~/Maildir:INDEX=/var/dovecot_indexes%h
namespace inbox { inbox = yes }
mmap_disable = yes dotlock_use_excl = no mail_fsync = always
mail_nfs_storage = no mail_nfs_index = no
lock_method = fcntl mail_temp_dir = /tmp mail_plugins = quota expire notify mail_log
mailbox_idle_check_interval = 30 secs mail_temp_scan_interval = 1w maildir_very_dirty_syncs = no
doveconf -n
