Solusi

1. Stop service zimbra dengan perintah

su - zimbra
zmcontrol stop

2. Periksa dan matikan paksa service yang masih berjalan dengan perintah berikut, menggunakan user (root):
a. Periksa service

ps ax | grep zimbra

b. Matikan paksa service

kill -9 <no pid>

3. Matikan paksa service yang sudah menggunakan port yang sama. dalam contoh ini port 993/tcp, 110/tcp, 995/tcp, 443/tcp dan 143/tcp dengan perintah berikut:

fuser -k 993/tcp
fuser -k 110/tcp
fuser -k 995/tcp
fuser -k 443/tcp
fuser -k 143/tcp

4. Jalankan kembali service zimbra

su - zimbra
zmcontrol start

Selesai
