Very slow command line operations on long uptime

[Alex]

I've a server where I'm trying to run a lot of virtual machines (25-30), with somewhat long uptime (some weeks) and what I see is a constant increase of the slowness of VBoxManage operations.

For example, on a fresh start the command "VBoxManage list runningvms" employs only 0.2 seconds but day after day the execution time rises and after some weeks the same command can employ even 60 seconds to complete.

This in turn gives problem with applications like phpvirtualbox that is unable to even reach the main screen (supposedly) due to various timeouts.

The only way to solve the problem is to shutdown all the machines, stop the vbox service, and restart it.
