the following formula in a button causes the entire box to panic and crash… this is INSANE!!! These boxes haven’t crashed in months… and one little formula does it? Anyone have a clue?
userexists:=@If(@IsError(@DbLookup(“”:“NoCache”;“”:“”;“membershipbyemailall”;pay_user;“lastname”;[ReturnDocumentUniqueID]));“no”;“yes”);
Subject: ReturnDocumentUniqueID Crashes Box!!!
Sorry I dont have a clue -but I can confirm this.
We have exactly the same problem here.
on Domino 6.0.3 on Linux 8.1
and I am “calmed” that we are not alone…
Since we did a change in a design element to a
@DbLookup with [ReturnDocumentUniqueID] and [FailSilent] the server involuntary crashes the http task.
