vsz_limit of service doveadm "ignored"?

8 Jul 2015


      Hello,
dovecot 2.2.18 on CentOS6.5
Jul 08 11:53:44 dsync-server(system): Fatal: master: service(doveadm):
child 32554 returned error 83 (Out of memory (service doveadm {
vsz_limit=521 MB }, you may need to increase it) - set CORE_OUTOFMEM=1
environment to get core dump)
I tried increasing to 1 G, 1024 M or even disabling via value of zero --
to no change.
Every other service has the famous 18446744073709551615 B limit.
default_vsz_limit = 2 G
The second node with the same setup/config is happily accepting a higher
value, since both
come from the same provisioning I cannot see (or expect) differences
around ulimit and thelike.
The configuration comes from a single file, so no include drama or such.
Any pointers why the setting is being ignored?
