So we have a java-tomcat setup running. During an upload onto the platform of a large file (eg, 31mb pdf) the Sophos savscand server process (both of them - there are always 2 running, this is standard apparently) on our RHEL5.5 system bogs down the entire system and consumes 700%+ cpu load.
Until the savscand processes are killed the system is on cpu overdrive.
