One of our production servers showing below error msg in Sql Server Log from last week,
SQL Server has encountered 20674 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file [D:\Databasefile.mdf] in database [Database] (11). The OS file handle is 0x0000000000000828. The offset of the latest long I/O is: 0x00001c3bde0000 and today in addition to the above one more msg,
BobMgr::GetBuf: Sort Big Output Buffer write not complete after 60 seconds.
is this the indication of a serious issue? How can we resolve this?
