Message Hi

 

After some playing around, I disabled Windows Vista DreamScene and the problem seems to have stopped, I will continue to monitor this for the next few days to see if this was the cause as very strange as not changed anything else on this system.

 

Thanks

Terry

Hi Stefan,

 

Good debugging advice. Terry, thanks for jumping in also. I couldn’t respond yesterday.

Stefen, I installed process mon, filtered, watched the TSVN window etc your recommended to Terry. Here is what I did and saw.

 

1. Log out, Log in

2. Setup the process monitor (PM) and TSVNCahe file crawl window, task manager etc to wathc cpu time (CPU)

 

TSNV is not taking any CPU, no PM events, no crawling messages.

 

3. Open the explorer window to my "problem" SVN work area. I tried not to touch my keyboard or mouse any more at this point.

 

4. Now, interesting..

 

- My browswer opened really slowly on the folder. I think redrew a few times. Didn’t notice any flashing icons this time but it the basic issues, things are really slow.

--TSVN CPU up to the 10-20%

- Continuous events in process monitor, I filtered out all registery events. These are all file IO. opening and closing files in by svn constantly.

- NO ACTIVITY on the crawler window. Very interesting.

- I think my explorer window is sometimes

redrawing. I'm not touching anything, just mainly watching the process monitor.

 

 

OK, after about 2 minutes I saved the process monitor as a CSV file. 108,000 events over about 3 minutes (7:55:07.3766917 PM -7:57:59.5240263 PM)

 

I brought in 64K lines to excel and sorted on path. I think it is stuck in a loop. It is visiting many, many different files. Most of them are the “entries” files but there are others. It is going to TSVNCache.exe of course but that is not interesting.

 

All I can do here is scan around a little and send you some observations I make. The whole file is 20MB. Let me know if there is anything specific you want or if you want the whole file tell me where to FTP.

 

Example file: T:\jkuhn\designs\​RFID\MX5_6p1\dfII​mx5t_sim\.svn\ent​ries)

 

 

Here is a small snipet of th the entries for this files total of 1600 entries spanning most of the 3 minutes.

That example snippet above just goes on like that for the whole duration of the capture. It just continues like this for the whole three minutes. But it is doing this many other files also, so I assume in each second is rapidly looping around and coming back to this one many times a second. The only error I see bleow s FAST_IO_DISALLOWED.

 

 

I do so it is looking at some non-version files at the problem level of my hierarchy and some different results that look “troubling”.

The cache is restarted because the explorer does not know whether a

folder is versioned or not. That's why it starts the cache and asks the

cache for that information. It doesn't matter whether you have a working

copy on the root or not - the cache is started anyway.
