Werk #15836: relax memory restrictions for fetcher process

In previous releases, an overly stringent memory limit for the fetcher process could result in frequent restarts and an excessive number of entries in the cmc.log file.

With this release, we have addressed the issue by adjusting the memory constraints. The fetcher process now has an increased memory limit, which should significantly reduce restarts and log verbosity, leading to improved stability and performance.
