We run postfix within VServers for years now, >180k good mails/day

problems with locks. Postfix is always current Debian stable postfix.
Filesystem went from ext3 to ext4 on DRBD on LVM.
The problems I ran into had mostly been open files limit which needed to
be increased. Checking google for your error leads to your posts on
postfix-users. Wietse Venemas hint on default_process_limit = 10
would hint very much to open files limit. I ran into these when I raised
the 100 max smtp processes to 2500. Back then no TLS had been involved,
this got configured only later.
It is an acient installation, updated over and over, but it says:
# cat /etc/vservers/NAME/rlimits/openfd
I hope this helps in tracking down your issue.
