After installing or upgrading Symantec Mail Security for Domino 8.0.7, 8.0.8 or 8.0.9 on a Domino server, and enabling Premium Antispam, it can be observed that the "conduit.exe" process is using almost all available system CPU every minute.
No errors reported by product logs.
When running a PerfMon capture of the CPU utilization by process "conduit.exe" on a Windows server, a graph similar to the following can be obtained:
- Windows 2003 32bit;
- Symantec Mail Security for Domino (SMSDOM) version 126.96.36.199 (x32/x64);
- Symantec Mail Security for Domino (SMSDOM) version 188.8.131.52 (x32/x64);
- Symantec Mail Security for Domino (SMSDOM) version 184.108.40.206 (x32/x64);
- Domino server versions 7.x or 8.x (x32/x64)
