Memory managemnet in SAP business connectors 4.7

Hi Experts,

I am working on SAP BC 4.7 . I had developed a service under a package. After few days I noticed that a record under that vanished automatically. After analysing I came to conclusion that it might be happening due to memory overload problem. When i checked through Administrator login in the server statistics, it shows used memory: 98%.

I tried resetting cache and also restarting server. But there was not much difference.

Queries:

1. Whether this is really related to memory.

2. How to reduce used memory and increase free memory.

3. Anyother suggestion relating to same.

Please do reply.

Thanks

Umesh
