We run two ProFTPD servers which provide load-balanced/fail-over SFTP/FTPS access to an s3fs-mounted partition.

During production operation (thousands of files, concurrent access patterns) we observe the following issues:

- s3fs C++ implementation contains memory leaks
- downloaded files via FTPS are sometimes empty/cropped
- versioned S3 buckets contain delete markers for every file uploaded
- directory listing via FTPS sometimes times out, same listing via SFTP doesn't

We are looking for a very experienced systems engineer who is interested in working on distributed systems, low-level optimizations and help us identify and solve the issues mentioned above.

A solution must include regression tests for the proposed bug fixes.

s3fs:   [obscured]  /p/s3fs/wiki/FuseOverAmazon
ProFTPD:   [obscured]  /

All software written for this project will be contributed back to s3fs/ProFTPD open source projects under GPL and can be mentioned as portfolio project.
