Can't start MCM (no replies)

Good afternoon everyone,
I'm having troubles when trying to start one of my mcm agents. Everything has been working smoothly for quite a long time, but it has suddenly stopped. When I try to start the mcmc this is what I see:

mysql@vm-leg-promesa-04-t:/var/lib/mysql $ /usr/mcm1.3.3/bin/mcmd --log-file=/var/log/mcm/mcmd.log --manager-directory=/var/mcm_data --daemon
mysql@vm-leg-promesa-04-t:/var/lib/mysql $ ps -ef | grep mcm
mysql 5485 1 99 15:53 ? 00:14:44 /usr/mcm1.3.3/libexec/mcmd --plugin-dir=/usr/mcm1.3.3/lib/mcmd --log-file=/var/log/mcm/mcmd.log --manager-directory=/var/mcm_data --daemon
mysql@vm-leg-promesa-04-t:/var/lib/mysql $

mysql@vm-leg-promesa-04-t:/var/lib/mysql $ tail -f /var/log/mcm/mcmd.log

Any idea of what's happening and how to fix it?
