Hello,
I found similar reports in this ML with values less than mine but was
not able to find the solution.
I checked size of all dovecot.* files in /var/mail and it is less
than
10Gb. Whole /var/mail dir is 1.8Tb.
With vsz_limit it crashes much earlier, this log with 275GB produced
by
setting vsz_limit = 0
Server has 192GB of RAM, can it be some bug?
