I am getting errors with XMPP on my Gentoo Hardened server. It runs and says it is running but when trying log many of these errors appear about a crash.
2019-11-01 10:56:54.748 [error] <0.563.0>@xmpp_idna:domain_utf8_to_ascii CRASH REPORT Process <0.563.0> with 0 neighbours exited with reason: call to undefined function xmpp_idna:domain_utf8_to_ascii(<<"XXXXXXXX">>) in p1_server:terminate/7 line 878
I suspect I have to install a dependency or something, or maybe the Gentoo ebuild is broken.
I recently updated ejabberd from 18.03 to 18.09 and this is when it started.
I am using dev-erlang/xmpp 1.4.2 on this system.
