Huge apache memory usage since update to 10.3

    we have a problem with apache prefork running all sites on the server as fast-cgi (about 500 Domains). The server was running stable with 4GB RAM until update of plesk.
    Since then, apache uses high amount of memory:

    30988 www-data 20 0 569m 324m 2396 S 4 6.3 0:00.02 apache2

    The php5-cgi requests have a normal memory consumption.

    I tried to see whats happening there with pmap, but over 500MB are marked as "[anon]"

    09296000 542488 rw--- 0000000009296000 000:00000 [ anon ]

    The other configuration:
    Debian 5.0.3
    PLESK 10.3.1
    KeepAlive On
    MaxKeepAliveRequests 100
    KeepAliveTimeout 5
    <IfModule mpm_prefork_module>
    StartServers 4
    MinSpareServers 2
    MaxSpareServers 5
    MaxClients 100
    MaxRequestsPerChild 4000

    Can someone see similar problems? How can I be sure that the configuration is ok? How can I find the memory-problem?
    Or maybe that's not a problem of PLESK?

    Thanks in advance!
