Problem
It has been identified that in some circumstances a user may encounter the following errors: Core Running Error SQL query details HRESULT hr=0x80040e31 Lock Request time out period exceeded or: Core Running Error SQL query details HRESULT hr=0x80040e31 Timeout expired NOTE: Some of the information detailed above may differ from that shown in the error message.
Resolution
The causes for either of these errors are usually one or more of the following:
  • The resources available on either the Server or Workstations.
  • The Antivirus software scanning all IRIS network traffic.
  • Improperly configured network cards. Server / Workstation Resources
  • Click Start and then click Run
  • Type in msinfo32 and click OK NOTE: For Windows Vista, Windows 7 and Windows Server 2008 you may need to click Start, type “msinfo32” into the search box and press enter.
  • On the System Summary section scroll down to the Memory figures on the right hand side
  • What are the values for a. Total Physical memory b. Available Physical Memory As a general rule if the available memory is less than about 10% of the total then this will indicate that the server or workstation in question is running low on resources and needs to be upgraded. Anti Virus Most Antivirus software has the facility to scan all network traffic. In the case of IRIS this can slow access to the SQL database and to IRIS. In most Antivirus programs you can set exclusions in the real-time or on-access scanning so that the mapped network drive used for IRIS (or the UNC path for IRIS) is excluded from the scanning. These exclusions should be set on the server and the workstations and should improve access times to IRIS and help reduce the frequency of Timeout errors. Network Sometimes an improperly configured network card on the server and / or workstations can cause network packet loss / slower performance. You should also check the network configuration so that a continuous connection is maintained. NOTE: IRIS is not responsible for the configuration of network settings. Your IT Support people should be able to assist you properly configuring your network settings.
