程序和一些别的没什么大的不同，但是memory leak很厉害，用了xml, sql, MSMQ，
force full GC以后好了一些，但是感觉还是有点问题，请问你们都用什么查memory
leak?

I know a software called BoundsChecker. But never use it before.

how to loadtest? you mena just keep it running?
it's funny that I disabled most part of it, still show some memory leak.
btw, the memory usage has stablized after the force full GC code...
it's really weird since I've never seen a c# program behaves like this b4..

What do you mean stablized after GC, do you only mean that GC collects all the
memory back or after GC it never leak again?
As far as I know, GC sometimes is not fast enough to collect all the garbage
and it may cause out of memory problem. the only thing you can do is to change
the design

the memory still grows but it shrinks from tiem to time, I have it running
for over 12 hours now, it didnot grow out of control.
probably, too many things allocated too fast, any way, it's good that it
works now. :D

it is independent of VS and it can be used for
.NET 1.1 applications.
check out this white paper.

for load test, if no third party tool is available,
ACT (which comes with VS Ent Arch Edi) can be used
for this. pretty handy tool
