JavaScript heap out of memory

[rthor]

Happened after not finding an import module:

Security context: 0xXXXXXX <JSObject>
    1: _parseMappings(aka SourceMapConsumer_parseMappings)

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Was the server running for a long time (many recompiles)? There was already a memory leak in webpack-hot-server-middleware, which I thought was fixed already.

Only about 3 hours, max...
