Restarting of SAP PRD server

Dear Team,

We are facing a issue with PRD server.

For last 20 days we restarted the PRD server for 3 times.

1)We restarted the server for TMS issue which is advised by SAP support team in one incident.

2)Another time we restarted the server for the issue in Procedure cache problem in DB which is also advised by SAP support team in another incident.

3)today server is restarted due to VMWare (physical server) problem.

Now i have one doubt how frequently we can restart the server and is there any future issues with this restarting of server.

Please give suggestions on this because this is very critical to us.

Frequently we are restarting the server production server.

Thanks&regards,

Patan Thavaheer.
