Hotplug/iface script gets not executed on boot up

Just opened a ticket there.

ntpclient: stucks after a couple calls in a row, causes hotplug script to stuck, other hotplug scripts are not called anymore

opened 05:40PM - 03 Jul 20 UTC

@thess **Environment:** VMware OpenWrt 19.07.3, r11063-85e04e9f46 ntpcli…ent - 2015_365-2 - NTP client for setting system time from NTP servers. **Description:** Multiple calls in a row of `/usr/sbin/ntpclient -c 1 -p 123 -i 2 -h 0.openwrt.pool.ntp.org` cause the ntpclient to stuck. This further causes that other hotplug scripts get not executed anymore, might cause security issues since it prevents the execution of firewall hotplug scripts. I am wondering if the `ntpclient` package is still required, since an ntpclient comes with the current version of OpenWRT, perhaps the package should get removed. Please look for more information there in the forum. https://forum.openwrt.org/t/hotplug-iface-script-gets-not-executed-on-boot-up/67312/48

Have you actually seen this on the iface hotplug scripts, or was that on scripts from any other section?
Just curious how this all works together.

I just took a look at my scripts and they are using ( )& to do the work, which makes the commands run in the background. My script is invoked many times and it is possible that the concurrent executions that I saw was not the hotplug, but my commands running in the background and detached from the hoplug context.

Thank you very much guys for your help to figure this out, as well as to help me to understand how this all this works together.
