A global memory buffer will be is allocated per EC. The size of the buffer is specified using an Execution Context property in the EC's configuration file located in the relevant container.

...

When several workflows are scheduled to run simultaneously, and the forwarding agents are assigned with the backlog function, there is a risk that the buffer may be too small. In such case, it is recommended that you increase the size of this property.


 

Info
titleExample - Setting a property to increase the maximum memory

To increase a maximum memory to 20 MB:

Code Block
mzsh topo set topo://container:<container>/pico:<pico>/val:config.properties.mz.forwarding.backlog.max_memory 20

You must restart the EC for the property to apply.

 

If no property is set, the default value of 10 MB is used. The amount allocated is printed out in the EC's log file. This memory does not affect the Java heap size and is used by the agent when holding a copy of the file being transferred.
