Description:

During our evaluation of parseable as a centralized logging solution, we have conducted two ingestion tests, sending 20GB and 80GB of log messages into the system, then performed searches over the dataset. During this time, memory usage (RSS) of the parseable process has increased:

  • during the first test (20 GB ingested): 1396 MB -> 3851MB
  • during the second test (80 GB ingested): 3855 MB -> 4739 MB

This suggests that there is a slow but steady memory leak.
