serctl creates a fifo where it expects ser's reply.
It seems the reply fifo created for "moni" has no write permissions for
"other".

Solutions:
 - change serctl (search for moni and add "chmod a+w $path" after
  mkfifo $path)
 - change umask before running serctl
 - run serctl sgid or suid ser
 - run ser as root (in /etc/init.d/ser change -u ser -g ser to -u root)
   -- not recommended
 - don't run serctl moni :-)
