How To Kill Your Livelink Server.... With Web Reports

Yes... this is true and very possible:
  • Run a long processing web report under the livelink.exe path and you'll get a CGI Timeout. 
    • Keep doing it and the server will not respond anymore. You'll have to restart services.
  • Send a null value to a search parameter based on an attribute field (if you are using search as your datasource)
    • This will cause an infinite loop. This is guaranteed when the attribute you are searching on is a required attribute. So much for depending on search as your datasource vs. old-fashioned LLATTRDATA convoluted-inner-join queries....
To avoid it: Use the llisapi.dll to run the reports. 

I brought down our production servers today. =]
