IOC Log: Fails to parse messages occassionally

As a developer I would like the IOC log not to fail to parse messages. To reproduce:
* Start an IBEX server
* Start a Galil IOC
* In the log messages for `IOCLOG` you will see something like:
```
[Tue Jan 28 17:19:01 2020] Failed to parse message from 127.0.0.1:58533 - GALIL_04INFOioclog2020-01-28T17:17:30.592+00:00

[Tue Jan 28 17:19:01 2020] Reason: null
```

Note that this is occurs for several IOCs, not just GALIL.

## Acceptance Criteria
The message no longer appears in the log. Data that is trying to be sent to the IOCLOG server is recorded successfully.
