inconsistent Timeout Expired with extended SP execute

All,
I've successfully executed my extended stored proc multiple times via
the following. If I directly execute(e.g., right-click 'Execute'
within my DB editor) this stored procedure, it runs everytime and
finishes in 1-2 seconds. If I try to execute the SP via my trigger, it
returns a 'Timeout Expired' message. But - not every time. I have got
the trigger to fire the SP a few (seemingly random) times without
timing out. Any help would be fantastic...
Pre-Thanks,
sara
my SP:
ALTER procedure dbo.WriteDNFiles
as
declare @.return varchar
EXEC @.return = master.dbo.XYRunProc 'C:\WRITE_DN_FILES.exe'
my trigger:
ALTER TRIGGER TriggerEmp
ON dbo.Employees
FOR INSERT, UPDATE
AS
exec WriteDNFilesHi sara
Running a program in a trigger is not a good idea as it will prolong the
transaction and there increase contention which could possibly be what you
are experiencing. You may want to make sure that you are not having any file
access problems if two process are wanting to call the program simultanously
.
Another general point is that you should change @.@.ROWCOUNT in the trigger to
see if anything has changed, if not don't call your procedure.
