Issue/Introduction
The IDS service process is linked with a default memory model, which allows for a virtual size for data sections of only up to 256MB. For normal system-level activities and most application purposes this is sufficient, however for large-scale environments where where there are hundreds of thousands of files monitored, this setting may be insufficient and can lead to out of memory errors and the service exiting or crashing during startup.
The problem can be predicted if the topas command shows the sisidsdaemon with a PgSp value approaching 256 MB (i.e. 180-256).

Cause
The IDS service process is linked with a default memory model, which allows for a virtual size for data sections of only up to 256MB.
Resolution
I believe that the default value was changed for this in 5.2.9.534 from 256 Megs to 1 Gig for earlier builds use the following work around:
In this case, the memory model should be changed for the IDS service with the following steps:
Applies To
AIX running 5.2.9 builds older than build 534.
