Hello.
So I got some news, in case anyone’s interested.
In dmesg we noticed this entry:
[ 124.382484] random: crng init done
[ 124.390444] random: 7 urandom warning(s) missed due to ratelimiting
This is what we found out about that:
These messages are the result of a bug that exhausts the entropy pool on your system.
This can cause delays in how quickly sshd (and maybe other services) become(s) available after boot.
So, we tried to compile Wt 4.9.1 and we disabled “ENABLE_SSL” option (ccmake), since we don’t use ssl.
And it works. The Wt app now starts after the reboot as it’s supposed to.
We’re not totally sure if disabling the “ENABLE_SSL” option is the thing that helped, but this is what we’ve done so far.
