ESDL Dual pipe service sometimes crashes

[lfse-slafleur]

This is a deterministic issue that happens on some ESDL files. Currently we do not have an example ESDL where this happens yet. Production has been altered to log ESDL's when the service is called until the issue is reproduced.

Relevant logs:

@edwinmatthijssen heb jij hier naar gekeken?

[edwinmatthijssen]

Nope, nog niet! het lijkt me op zich wel handig als er een voorbeeld ESDL is waarbij dit gebeurt....

[ewoudwerkman]

Is there an ESDL available to test?
