It is known that on the SSR-130, this can result in high memory alarms and potentially degrade the performance of some control processes. + +The IDP engine on SSR-130 will use an additional 2GB on startup (increasing from 1GB to 3GB) and will retain this usage until disabled. + +### Recommendation +It is recommended to avoid upgrading to version 6.3.3-r2 if you are using IDP and the device is an SSR-130 until the issue can be resolved. + +### Release Notes +N/A + +### Severity +
