sorry, Rivet_InitCore is called from Rivet_PerInterpInit which in
turn is called from any bridge. But the question is still do you have
other errors when you start up the server?

no, the error is quite different ( command ::rivet::apache_log_error
not found) and it's generated from within the worker bridge (without
a working bridge no Tcl stuff can be evaluated). Do you have more
errors *before" this one? The call to Rivet_InitCore should set up
the whole command set and it's compiled into mod_rivet.so

I have tried to enable rivet under worker mpm, but I am getting an error:
[:error] [pid 5963:tid 140477525366528] (20014)Internal error (specific
information not available): mod_rivet: Error running GlobalInitScript
'set ::PaloServices 0; source -encoding utf-8
/var/www/rivet/server/server_init.tcl': invalid command name
"::rivet::apache_log_error"
while executing\n"::rivet::apache_log_error warning "Server Init
loaded under PID [pid]""
(file "/var/www/rivet/server/server_init.tcl" line 34)\n invoked
from within\n"source -encoding utf-8
/var/www/rivet/server/server_init.tcl"
So, something is wrong. Rivet did not find its worker mpm library? It is
in the same directory as worker:
root@fedser petasis]# ls /usr/lib64/rivet3.0/site-packages/mod_rivet/mpm/
rivet_lazy_mpm.so rivet_prefork_mpm.so rivet_worker_mpm.so
