Applescript Limit to calls?

Question

I have an Applescript app that worked in the past for modifying a few thousand files while reading from a Filemaker database. When I updated to Mavericks, it started erroring out. Eventually I narrowed it down by making a simple script that tries to modify the same file a few thousand times:
<code>
--  IODAppDelegate.applescript
--  MavericksTester
script IODAppDelegate
property parent : class "NSObject"
on run
tell current application to set i to 1
tell current application to set fileToWrite to "/Users/UserName/Desktop/hi.txt"
repeat while i ≤ 100000
tell current application to set textToWrite to "hi " & i as text
try
do shell script "echo " & quoted form of textToWrite & " >> " & fileToWrite password "###" with administrator privileges
on error errStr number errNum
display dialog ("error writing to hi file for " & i & " error: " & errNum as text) & " " & errStr
end try
set i to i + 1
end repeat
end run
on applicationWillFinishLaunching:aNotification
-- Insert code here to initialize your application before any files are opened
run
delay 3
tell current application's NSApp to terminate:me
end applicationWillFinishLaunching:
on applicationShouldTerminate:sender
-- Insert code here to do any housekeeping before your application quits
return current application's NSTerminateNow
end applicationShouldTerminate:
on applicationShouldTerminateAfterLastWindowClosed:notif
return true
end applicationShouldTerminateAfterLastWindowClosed:
end script
</code>
It stops after doing this 253 times. I've tried it on multiple machines running Mavericks with the same result. The message is: Security API failed with error -60008.
I appreciate any and all assistance on this.
Thanks

I'm confused about what your ultimate goal is, but the way you're going about this test is peculiar. using do shell script and echo to write to a file is unnecessarily indirect and probably where the error is creeping in.  If you write the script as follows it works just fine.
on run
          set fileToWrite to "/Users/tedwrigley/Test area/hi.txt"
          set fp to open for access fileToWrite with write permission
          repeat with i from 1 to 100000
                    set textToWrite to "hi " & i as text
                    try
                              write quoted form of textToWrite & " >> " to fileToWrite
                    on error errStr number errNum
                              display dialog ("error writing to hi file for " & i & " error: " & errNum as text) & " " & errStr
                    end try
          end repeat
  close access fp
end run
