SAP Error About TemSe ?

Our SAP Production system went down last night and Im not sure exactly why.

I checked the servers event viewer but no good information.

Then I ran SM21 and did a view of the event log during the duration of one hour when it happened yesterday.

I get this:

Database Error: TemSe->XRTAB(4)->64 For Table TST01 key M:\usr\sap....

When I dig deeper into the error message it just says Database error:

TemSe->&A (Database access module) &B- Function Number &C Error Number for table &D key &A.

I hope I posted this in the right area as I did not find an SAP Basis Forum.

By the way I ran SPAD and did a consistency check.

It came back with 20 TemSe object names. Should these be deleted?

What exactly are these ? I am very new to SAP
