Hi,

Am developing an ASP.Net application using c#. At one point I need to bind a
dataset to my DataGrid and display to the user. When the numbers of rows are
less there is no problem in binding the datagrid.
But when the number of rows is a large number I tested for 56K rows. The
DataBind() line generates an error and the aspnet_wp.exe restarts itself
automatically.

An application event log is created as : aspnet_wp.exe (PID: 3336) was
recycled because memory consumption exceeded the 301 MB (60 percent of
available RAM).

I have implemented paging PageSize 500.

The test server is a 512MB RAM, 2.39GHz, 15GB Hard disk machine.

Is the error because of the test server configuration or is there a limit in
the number of rows that can be bound to a datagrid.

Any help is appreciated..

no the worker process was recycled because when you touched the dataset and
it was sufficiently heavy (by frameworks standard - based on your machine
spec). it think its 60% of available memory usage (or something like that).
try increasing virtual memory though i would suggest just add a whole loads
of RAM sticks..

I prefer 1GB+ RAM on my dev / server pcs.the more the better. if you are
contrained and cant add RAM then consider a way to limit the records being
sent.. ie use some funky database side paging.

As the error states, ASP.Net's worker process recycled itself because you
exceeded the 60% limit. You can change this limit by going to:
C:\WINNT\Microsoft.NET\Framework\v1.1.4322\CONFIG (windows on XP and you
might have a different version) and editing the machine.config file. Look
for <processModel which has a memoryLimit set to "60"

However, do note that putting this higher (even to 100) is a poor bandaid.
If three users hit the site at the same time, they'll cause the same thing
to happen. I believe in IIS 6.0 you have a more refined control over this
(physical and virtual memory limits)

This thread might be of some use:
