It's unlikely that they leak memory, but in case that worries, you can do two things: configure vsz_limit for the service(s), or configure service_count for the service(s). The first one will slay the login processes, disconnecting everyone, if there is a leak, the second one will recycle the process at some point. Since 2.3.19, you can also use https://doc.dovecot.org/settings/core/#core_setting-process_shutdown_filter to shutdown the process if it's memory consumption goes too high.
