LuaEngine: Script failure

[TheThommy]

Hi there,

I´ve just installed ntnopng on a Proxmox-VE and am unable to start it. The service itself is starting up without any errors, but few seconds later it comes to Errors:
[LuaEngine.cpp:594] WARNING: Script failure [/usr/share/ntopng/scripts/callbacks/system/startup.lua][/usr/share/ntopng/scripts/lua/modules/pools/pools.lua:12: module 'recipients' not found:#012#011no

When trying to load the website, connection gets refused from server.

Are there any ideas on how to solve this?

Thanks a lot

It seems this installation is not clean. How did you install it? Make sure to use instructions at packages.ntop.org

[TheThommy]

downloaded the deb from web, installed it and did an apt upgrade afterwards which also installed some more depencies. as of now, apt wouldn´t install more / other

[simonemainardi]

can't install just downloading the deb. Please, follow step by step the instructions at packages.ntop.org and report.

that´s how I did it. works fine at 1 server, doesn´t works for 2 more. maybe the last 2 line are relevant?

[cannot open /usr/share/ntopng/scripts/callbacks/system/timeseries.lua: Too many open files]

However; the limits shouldn´t be a problem?!
cat /proc/sys/fs/file-max
9223372036854775807

cat /etc/security/limits.conf

• soft nproc 65535
• hard nproc 65535
• soft nofile 65535
• hard nofile 65535

[simonemainardi]

Do you see any difference in limits.conf between the working and non-working servers?
