regularly crashes

We are on build 6012 running on an MSSQL database.. Occasionally, probably once a week actually, Servicedesk will crash and will require the services to be restarted. This is something we've been dealing as we've been anticipating the release of the migration pack for v7.0.0. However, when we restarted it this morning, we received approximately 20 emails that had been sent to our helpdesk since Monday that we had not gotten at all. This is the first time this has ever happened, however it concerns us that something else may have happened.

I figure I'll be told that since the migration pack is on its way to just wait for that, but I thought to ask and see if there is some fix for this problem.
