It was a bad idea, I know, although I really knew it later ...
I had some performance problems, I contacted vbulletin.com, we saw that I had some tables (without any explanation in innodb) I was advised to change all to innodb except 3 that must be myisam and 2 that are memory.
But I only converted the vb tables, not the mods.
From that moment, I had more problems, some errors that I did not know why, mods (new) that I could not install and / or that gave errors, others that I could not uninstall.
Unstable server performance, peaks of low CPU load peaks of high cpu load (and I have a VPS with leftover resources for my site).
And then I saw the problem in arcade and some other more as indicated above.
After several days / weeks with innodb and see the instability, in a certain way, produced in server, I decide to reconfigure the tables as by default they would be in a 0 installation, I mean, myisam.
From that moment, all my problems disappeared, everything worked perfectly again, both on the server (cpu loads) and on my site.
Although I see that, the installation of a mod or uninstall, for example, the arcade one, takes a long time, before it did not take that long, but now it does it correctly, installs and uninstalls without errors.
The only problem I have is the arcade one.

What is your exact environment now?
