2143542 - ODBC: Internal error thrown when command timeout occurs in multi-threaded application each session calling stored procedures with nested procedures and reource accessed is locked - SAP SDK

Symptom

  • Under certain timing conditions, such as when the ASE is local to application, multi-threaded app will throw these errors on some of the threads when the command timeout/cancel is issued to ASE:

The command has timed out.
Operation Canceled
Internal Error

  • Occurs when several similar stored procedures performing multiple functions, are blocked during an update command. 
  • If the procedure has sent responses back to client, it can be interupted by the cancel during read timeout. 
  • Sometimes this occurs with the Internal Error message:

Thread[1]: ProcStmt: exec sp_gemed 2, 'two'
Thread[7]: Error occured in SQLExecSeq: SQLExecDirect:
