php-fpm crashing when deleting multiple sites at once

Hi there,
I noticed that sometimes php-7.0-fpm crashes, when I delete some sites at once. It just happened again and here are the logs from that moment:

Code:

[19-Nov-2018 15:42:03] NOTICE: Reloading in progress ...
[19-Nov-2018 15:42:03] NOTICE: reloading: execvp("/usr/sbin/php-fpm7.0", {"/usr/sbin/php-fpm7.0", "--nodaemonize", "--fpm-config", "/etc/php/7.0/fpm/php-fpm.conf"})
[19-Nov-2018 15:42:04] ERROR: failed to open configuration file '/etc/php/7.0/fpm/pool.d/web1700.conf': No such file or directory (2)

In the sys_datalog-table I see that I deleted domain_id:1515 at timestamp 1542638475 and domain_id:1700 at 1542638484
Seems as if the web1700.conf was already deleted when the reload from web1515 took place?
Perhaps it is necessary to wait with deletion of pool.d/xxx.conf until php-fpm.conf is written. But thats not my field of expertise do you need any other data from me to get into it?
