[Libvirt-cim] About provProcs value problem for sblim-sfcb cim server

Hi all, I met a problem for sblim-sfcb cim server. In the configuration file, the default value of 'provProcs' is 32. While running cimtest, there are many failed cases with error "Provider not found or not loadable", eg: HostedAccessPoint - 01_forward.py: FAIL ERROR - No kvmrsap instance returned Provider not found or not loadable -------------------------------------------------------------------- HostedAccessPoint - 02_reverse.py: FAIL ERROR - No kvmrsap instance returned Provider not found or not loadable -------------------------------------------------------------------- After I change the value of 'provProcs' to 64, these cases pass. The provProcs is 'Max number of provider processes', and http://doc.opensuse.org/products/draft/SLES/SLES-admin_sd_draft/cha.wbem.... said 'if a new incoming request requires loading a new provider, then one of the existing providers will first be automatically unloaded' So I am wondering that why does sblim-sfcb not automatically unload the existing providers, and load the specified provider for case 'HostedAccessPoint - 01_forward.py'. Is it a real problem?
