Lighttpd keep crashing after last update

After last update my two omnias keep crashing lighttpd
SW version for omnias is:

Turris OS version 3.7.3
Kernel version 4.4.79-967673b9d511e4292e3bcb76c9e064bc-0

I cant acces foris and luci

logs :

Internet connection works but I cant acces luci + foris

About 30s after rebooting into the new kernel, this was logged:

2017-08-05T22:35:18-07:00 info procd[]: Instance lighttpd::instance1 s in a crash loop 6 crashes, 3 seconds since last crash

but foris & luci are working ok so apparently it was able to recover.

Kernel Version 4.4.79-967673b9d511e4292e3bcb76c9e064bc-0

I try update opkg and run updater again

after some time still crashing

This problem come again and again after every reboot…

after every reboot I must restart lighttpd interface, this issues come with 3.7.3 update

Strange. I saw this post. My router had no such problem.
But after update.And some more expoloration. I do have pi-hole inside ubuntu LXC. And I had to restart lighttpd there.
This had never happened before.

Have you tired to start it manually, not with script, via /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf?

I will try if lighttpd crash again

Today I want change one port in firewall setings… again I cant acces web UI

I dont find any things whats going on my omnia. as ´´fix´´ I made simple cron for lighttpd restart … is it safe?
