Maximum number of memory segments that Notes can support has been exceeded

Hi,

I am getting the following errors on the server:

Unable to retrieve activity trends configuration.: Insufficient memory.

Replicator was unable to obtain any scheduling information: Maximum number of memory segments that Notes can support has been exceeded

Admin Process: File name: Maximum number of memory segments that Notes can support has been exceeded

Please let me know if there is some way to resolve this issue apart from Server upgrade.

If Server upgrade is required then which version

Thanks,

Mago
