SYMPTOMS
When you use third party IFilter components with Index Server, the Cidaemon process may consume a large amount of memory. This may cause a low memory situation on the server, and the server processing may slow down.



CAUSE
The Cidaemon process is designed as a sandbox for IFilter components, which means that every IFilter is loaded into this process. Thus, if an IFilter is poorly designed or coded, the IFilter can cause Cidaemon to consume a large amount of memory.



RESOLUTION
To resolve this problem, contact the IFilter vendor, and request a fixed IFilter component.



WORKAROUND
Index Service 3.0 (Microsoft Windows 2000) introduces a new mechanism that limits the memory usage of the Cidaemon process. The Cisvc process monitors the memory consumption of the Cidaemon process. If the Cidaemon exceeds 40 megabytes (MB) of memory usage, the Cisvc process automatically ends and restarts the Cidaemon process. This mechanism prevents the server from reaching a low memory situation and a slow down in server processing.
