I'm running a very simple, timestamp-based bash script under logstash's exec input. After a few hours, I stop receiving data, and the following appears in the log

```
[ERROR][logstash.inputs.exec] Error while running command {:command=>"/etc/logstash/scripts/cf_edge_poll.sh", :e=>#<Errno::ENOMEM: Cannot all

```

The system is running in Azure, 14GB memory, with 7GB max on java settings.

Updating to the latest version does not help.

Advice is welcome.

Updated heap memory, still the same results. Advice is welcome.

Thank you
