MS SQL server is going down frequently(10 days of gap) with exception message: "A severe error occurred on the current command. The results, if any, should be discarded".

Question

MS SQL server is going down frequently(10 days of gap) with exception message: "A severe error occurred
on the current command. The results, if any, should be discarded". We are facing this issue for past two month.But funny thing is server will be up automatically with out any service restart manually.  Also if we try to restart the SQL
server service manually then SQL server will be in a dead lock situation and it will not come up even if we wait for long time. Then we should do a windows server machine restart to
make the SQL sever up. As a suggestion from Microsoft to fix this kind of similar issue,
we have installed service pack 3 for SQL Server. But even after we are facing same issue.
Server Details:
Server OS: Windows Server 2008 R2
Two type of database servers are installed on server:
1. MS SQL Server 2008 R2
2. My SQL
Also Reporting server is configured for the purpose of generating SSRS report from a dot net website.
 NOTE:Immediately after the data retrieval/save, we are closing the connection explicitly by the
application.
we have checked the windows event log and below are the details:

Could anybody can suggest any kind of fix for this issue? Thanks in advance.

Hi YesYemPee,
I have tried but still not clear about your issue, I would like you provide more details information about your issue based on below points to better analysis about the issue:
What action did you do and caused the error "A severe error occurred on the current command. The results, if any, should be discarded", did you run report on the web application or something else then the error happen?
If you rendering the report and got the error, please try to provide us more error information in the log files which path like:
C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles
If it is not the case in step1, Please try to provide SQL Server Error log(SQL Server Logs) and more details information.
If you still have any problem, please feel free to ask.
