About the maximum number of parallel episodic replication jobs
The maximum number of episodic replication jobs is 64, but there are stricter limits on the number of episodic replication jobs that can be running in parallel at the same time. Episodic replication uses a RAM-based file system for storing the transit messages. Each GB of this RAM-based file system can accommodate up to eight parallel running jobs. The default size of this file system depends upon the amount of physical memory of the node on which episodic replication is running. If the physical memory is less than 5 GB, episodic replication limits its maximum usage for storing messages to 1 GB of memory, which means the user can run up to eight episodic replication jobs in parallel at the same time. If the physical memory is between 5 GB to 10 GB, episodic replication limits its maximum usage for storing messages to 2 GB of memory, which means you can run up to 16 episodic replication jobs in parallel. If the physical memory is greater than 10 GB, episodic replication limits its maximum usage for storing messages to 4 GB of memory, which means you can run up to 32 episodic replication jobs in parallel at the same time.
