Here is what I get after starting cppserv:
unix  2      [ ACC ]     STREAM     LISTENING     75497  /tmp/cppserv.sock

When I start servlet in the browser, it adds:
unix  3      [ ]         STREAM     CONNECTED     75673  /tmp/cppserv.sock

I did 'sudo make install' in my cppserv/ directory, got

Linking mod_cserv
Installing debug/./src/mod_cppserv/mod_cserv.so into
//usr/lib64/apache/mod_cserv.so

message, but it didn't resolve the issue.

Another thing, after starting cppserv I get debug "Connecting to DB"
message which is used in my uudb class' constructor, if it may lead to any
clues.
