APAR status
Closed as program error.
Error description
Near the end of the pre-rendering process, any required resources are saved to disk. It has been observed that the memory used by the WCM server increases steady from this point till the end of the pre-rendering process where that memory is then released. This defect is to address that memory spike as it can lead to out of memory errors. During the resource pre-rendering process, the JCR node cache wasn't being periodically flushed and the progress was always keeping track of each resource that was pre-rendered which isn't required when not overwriting the existing pre-rendering directory.
Local fix
The resource pre-rendering process was modified to periodically flush the JCR node cache as well as only keep track of pre-rendered resources when connect.moduleconfig.cacher.overwritecache is set to true.
