Issue/Introduction

For a particular user, they try to create a Workbench workarea from a certain repository path and it goes so far and then just stops. Not the same point every time. Opening the project from Visual Studio shows the same problem.

Cause


Looking at your hco.log that you sent me, the last line is: 

02/13 11:22:29 - In Reply() - Calling TipcConnFlush() 

I should be seeing a “In Reply() - TipcConnFlush() returned” message just after that, but it’s not there, so this appears to be where it’s hanging. 

If this is observed when running hco with the "-tr" option, this method usually gets blocked if TCP socket’s internal buffer is full. 

 

Environment

CA Harvest SCM v12.5

Resolution

Can you please check the output of the following command on a test Windows 2008 R2 machine in a command prompt? 

netsh int tcp show global 

The output on one of our 2008 R2 machine is 

TCP Global Parameters 
---------------------------------------------- 
Receive-Side Scaling State : enabled 
Chimney Offload State : automatic 
NetDMA State : enabled 
Direct Cache Acess (DCA) : disabled 
Receive Window Auto-Tuning Level : normal 
Add-On Congestion Control Provider : ctcp 
ECN Capability : disabled 
RFC 1323 Timestamps : disabled 

If you get the below message while issuing “netsh int tcp show global” 

** The above autotuninglevel setting is the result of Windows Scaling heuristics 
overriding any local/policy configuration on at least one profile. 

Then, please issue the command “netsh int tcp set heuristics disabled”. 

If the Receive Window Auto-Tuning Level parameter is normal, then please run following command to disable it and then try the checkout with hco -tr option. If the command is accepted by the OS you will see an "Ok." on a new line. 

netsh interface tcp set global autotuninglevel=disabled 

This parameter was added for Windows 2008 and we suspect that this could be causing some problem. 
If the checkout still hangs, we will review the remaining parameters.
