hi jcrow,
you can just use the “Download agent output”-option on your Check_MK Service:
Unless the error appears again, there is no chance to review the problem itself.
If it appears, just download the agent and take a look into the mssql-section. If you can’t find the
problem by yourself, i would recommend to post the myssql-section of your agent output, so we all can take a look onto it.
