Looks like there are issues here.. in my solution with some 750 source files (all .net) it tyakes about 30 seconds now to end a class header comment.

The CPU utilization on my Dual P4, 3.0Ghz computer goes to about 60%. Looking in task manager, the Memory utilization is over 1Gig!

This is after rebuilding the symbols.

On more thing... When I looked, I had less than a Gig left of disk space on drive C, when I exited, my space jumped by almost 4gig. Its not my page file because I have it set to be a specific size (3gig); my available memory in my system is 2gig.

odd. i am not seeing any such problems on a relatively large pure C++ solution in VS 2003 with VA 1422.

it is recommended that you upgrade from 1421 to 1422 since it fixes a frequent crash.

http://forum.wholetomato.com/forum/topic.asp?TOPIC_ID=3932

presuming this problem happens regularly can you look and see where the extra hard drive space is being used? it could be the ncb file, but that is a lot of HD space for one file to consume.

which IDE are you using?

Upgrading now. The NCB was the first place I looked... that's not it. I'll let you know after the upgrade if I am still having the problem.

Upgraded, it appears to behave somewhat differently... now I get a Runtime Error - Pure virtual function call; I have gotten this a few times and only with VAX Build 1422 is installed and enabled.

I Upgraded to 1423 and have the same issue, it appears that it does not eat memory quite as fast, but it is virtually unusable after about 10 minutes of editting... I get pauses of 2-3 seconds while editting inside the body of functions.

Oh, Feline... the directory that is taking up all my space is the c:\\programfiles\\visualssistx\\vc7\\cache... its at about 2.48GB right now, memory usage for DevStudio is at was at about 1gig before I restarted it. I am going to let it build up and leave it sit when I go to lunch today to see if it ever comes down with no activity.

File distribution:

761 C# files totalling 7,163,121 bytes
52 .CPP files totalling 521,070 bytes
60 .h files totalling 724,026 bytes
5 IDL files totalling 52,433 bytes
53 .Net Projects
5 Native C++ Projects

My NCB file is now at 4,194,304. (deleted it this morning and recreated it)

A note has also been sent to support.
