Hi ya,
What version of EV are you running? Are you actually seeing MAPI issues?
I reboot is a bit of overkill. In version prior to EV 8 it was necessary to stop the services/tasks to put the application in Read Only mode but now with EV 8 you can put EV in back up mode with Powershell scripts.
If you are seeing MAPI issues at the most I think a Restart of the Task Controller Service would suffice.

How to restart Enterprise Vault MAPI Tasks automatically.
Details:
Enterprise Vault MAPI tasks such as the Exchange Journaling Task and Exchange Mailbox Archiving Task can be configured to restart automatically on an interval or when MAPI Mutex errors are reported.
Resolution:
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry be made prior to making any registry changes
To restart MAPI tasks on an interval create the following registry key:
HKEY_LOCAL_MACHINE\Software\KVS\Enterprise Vault\Agents\
Value Name: RestartAllMAPITaskIntervalMins
Data Type: DWORD
Specify the number of minutes (decimal) to wait before restarting the MAPI tasks.
To restart MAPI tasks after a MAPI Mutex error is reported set the following registry key:
HKEY_LOCAL_MACHINE\Software\KVS\Enterprise Vault\Agents\
Value Name: RestartOnMAPIMutexError
Data Type: DWORD
0 = (Default) Do not restart MAPI Tasks when a MAPI Mutex error is reported.
1 = Restart MAPI Tasks when MAPI Mutex error is reported.
After performing the registry modification, restart the Enterprise Vault Task Controller service for the changes to take effect.
