"TCS has stopped working" error when starting TruClient IE script in LR12

Actually, I have a ton of issues with TC in IE. And TC in Firefox doesn't even replay for me. But let's start small, and figure out this error to start.

 

This happens sporadically in interactive mode, Usually, I just have to close the FF editor and reopen. Sometimes I have to restart Vugen.

 

If I run the script non-interactively from Vugen, I get a different sporadic error, "IPC connection to browser process is lost".

 

Maybe these are related errors, maybe not. In any case, I am hurting, and I can't show ROI of a broken product. Even if I have been using LR for 10 years and TC for 2.

Hi,

It is hard to tell but my hunch is either setup or some enviornmental issue.

Can you try to uninstall/install? Do you have some other HP products on the same machine? If upgraded from previous LR versions what was the install sequence? Did it work with IE9? on other machines? is it specific to some application?

 

Thanks.

This is a clean box that I received on my first day of work in April. LR12 was the first application that I installed.

I'll try turning it off and on again.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

Same issue after a clean uninstall/delete directories/reinstall.


In FF, replay fails 100% of the time with:

Virtual User Script started at : 2014-06-19 13:09:46 Starting action vuser_init. TruClient Replay for LoadRunner 12.0.0, build 1362. OS: Windows 7, initialized on 2014/06/19 at 13:09:46 (0000.000s)

In IE, replay fails less often with:

t=00090489ms: Error -205177:  IPC connection to browser process is lost    [MsgId: MERR-205177]
Ending action Action.
Ending iteration 2.

Slightly different error now in TC_FF on replay:

 

Error: TransDataLoggerExt failed to initialize TransactionDataToSQLite class
Error: For more information, see TransactionsData.log
Warning: Extension trans_data_logger_ext.dll reports error -1 on call to function ExtPerThreadInitialize
Error: Vuser failed to initialize extension trans_data_logger_ext.dll.

Hi James,

 

There should be a file named TransactionsData.log on your script directory, can you please share its content?

 

Thanks,

Roy

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

I am not seeing that file in either my TC_FF scripts, nor my TC_IE scripts.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

I have reverted to 11.52 and am seeing different errors, but similar enough in severity to make TruClient unusable.

The difference is that in 11.52 TC_FF I can at least get Firebug to work, and I can replay a single step. Other than that, it records and that is it.

I have done as much root cause analysis in the areas of virus protection, DEP, firewalls, and other interfering programs as I can. I'm hoping that someone has seen a issue similar to this and has a suggestion.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

The answer is:

 

Sophos Endpoint and Security Control was interfering with the operation of HP LoadRunner TruClient.

For those who have this virus protection, I will post my findings when I have a solution.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

Have you seen similar problems with McAfee?  I'm experiencing a similar error but have McAfee installed instead.  In my environment, my TruClient script runs under load for a while and then gets the "TCS has stopped working" error and one vUser dies.  The rest continue.  

 

Any help you might suggest would be greatly appreciated.

Hi,

Either disable the AV and try or add LR executables to the white lists.

mdrv.exe, TcWebIeLauncher.exe processes

 

Thanks.

James, have you had any more trouble, or luck with this?

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

Since I started running TruClient on a VM with only Avast, I no longer see this issue.

 

There is definitely a vulnerability to interprocess communication interrpuption. TruClient needs constant connectity to that browser instance, or things get nutty. I think some corprorate security settings are too tight for TruClient to run effectively.

Veyr interesting, thanks, James. I suppose you could consider the behavior involved there a bit "malware-like," I guess I'm not shocked it can raise flags.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

I get error "TCS has stopped working" most of the times when I open a script in VuGen and click on button "Develop Script". Problem was solved by adding "mrdv.exe" and "TcWebIELauncher.exe" to the ScriptScan whitelist of McAfee.

 

McAfee scan log was empty (.exe are clean), but the ScriptScan log of McAfee had an entry. This is why the exectuables were not whitelisted at the top level, but only at the ScriptScan level.

Re: "TCS has stopped working" error when starting TruClient IE script in LR12

I had the TCS stopped working issue starting last week after a security update for MIcrosoft Windows was installed.  HP support advised that I remove the security update KB3038314 and reboot.  This resolved the issue.

YES

I looked at the updates that our operators pushed to my system and sure enough KB3038314 was there.

Removed it, and I now have TC working again.

 

I now have a post-it on my monitor with the words "KB3038314 - TC Killer" so I know what to look for next time they push updates.

 

THANK YOU NeilChikode

Add the KB3049563 to the black list, is killing the IE TruClient scripts like the KB3038314.

Hi,

 

Can you please share some documentation on these recommendations?

 

My desktop team needs some kind of documentation from HP or proof to disable AV or whitelist mdrv.exe and TcWebIELaucher.exe as disabling AV is against the policy.

 

 

Thanks,
