I would like to implement an IP SLA shadow router running pathEcho application with 365 IP SLA instances. I tried it on a Cisco2811 with 64MB flash and 256MB memory. The problem is that the Cisco2811 cannot handle all the operation when put into production. The router cannot be access/managed anymore. Any suggestion will be much appreciated on what platform I can use to support all the IP SLA instances that I would like to run.
How are you starting these 365 IP SLA sessions? Simultaneous or sequentially?
Q. What is a dedicated (shadow) SLAs router? What are the benefits?
So, your device is recommended by Cisco to be use as dedicated SLA router.
Regarding the CPU and memory utilisation:

Cisco IOS Software 12.2 and above

More you can find here:
Your router resources should support your 365 IP SLA connections. Even if you start them simultaneously and admit that these are consuming all router resources, you will have your connection to the router stuck for some seconds and then you shoul gain the connectivity again. Check with:
show proc cpu history
show proc memory sorted
If you have spikes of utilisation or permanent memory and CPU are used to the limit.
More than this, it would help if you can paste here an excerpt about your IP SLA session configuration.
