Hi all,

Here is my observation of recyclation of worker process aspnet_wp.exe.
Server: Win2000, 2GB RAM, 2xCPU
Installed .Net Framework 1.1, ASP.NET 1.1 application

When memoryLimit="60" and allocating 100MB chunks of data ( no change for GC to free ), TaskManager shows aspnet_wp.exe contantly cca 90MB, yet MEM Usage grows by 100MB. After some time I end up with OutOfMemeoryException.

When memoryLimit="45" and doing the same, after some time worker process IS recycled, MEM Usage drops down and new wp with new PID is started.

Can you explain me why it doesn't work with more that 49% ???

Your baseline is incorrect. Task manager is not the utility to use to
monitor memory consumption. You need to use something more accurate like the
memory profiler available from microsoft.

Memory and object disposal are complicated at best. Use the memory profiler
and if you results are roughly the same re-post here
