I wasnâ€™t going crazyâ€¦ I finally tracked it down.
I was stress testing a new application by submitting lpr.exe jobs from windows clients using lpr.exe I tried it from:
- Windows 7 Ultimate 64 bit
- Windows Server 2008 (32 and 64bit)
Using a windows batch file:
@echo off for /L %%i in (1,1,25) do ( echo %%i rem Use ping to put a delay in rem ping -n 1 -w 5000 220.127.116.11 lpr -S 10.11.12.13 -P printqueue print_this.txt )
The jobs would freeze as it appears now at the 11th job.
I was seeing Event ID 4227 http://technet.microsoft.com/en-us/library/cc735929(WS.10).aspx in the lpr.exe client System logs
On each client I added the following to the registry and all of a sudden I can submit 25 jobs as quickly as formtrap can receive them.
