#18726 Assertion 'rc == 0' failed in mdb_page_dirty() Issue created by jtilahun Describe the bug Attempting the

export

goal with the

--no-pantsd

argument results in failure on my system with the below error message:

jtilahun@JTN86G3:~/devel/monorepo$ ./pants --print-stacktrace --no-export-symlink-python-virtualenv --no-pantsd export --resolve=python-default
/github/home/.cargo/git/checkouts/lmdb-rs-369bfd26153a2575/6ae7a55/lmdb-sys/lmdb/libraries/liblmdb/m:2126: Assertion 'rc == 0' failed in mdb_page_dirty()
Aborted (core dumped)

The error message indicates a possible relation to other bug reports, e.g. bmatsuo/lmdb-go/issues/131. Pants version 2.15.0 OS Linux Additional info The context is that attempting the

export

goal without the

--no-pantsd

argument results in failure on my system with the below error message:

native_engine.PantsdClientException: The pantsd process was killed during the run.

If this was not intentionally done by you, Pants may have been killed by the operating system due to memory overconsumption (i.e. OOM-killed). If you keep seeing this error message, try the troubleshooting steps below. If none of those help, please consider filing a GitHub issue or reaching out on Slack so that we can investigate the possible memory overconsumption (<https://www.pantsbuild.org/docs/getting-help>).
 - Exit other applications, including applications running in the background.
 - Set the global option `--pantsd-max-memory-usage` to reduce Pantsd's memory consumption by retaining less in its in-memory cache (run `./pants help-advanced global`).
 - Disable pantsd with the global option `--no-pantsd` to avoid persisting memory across Pants runs, although you will miss out on additional caching.

According to the error message, disabling pantsd with the global option

--no-pantsd

is one possible troubleshooting step. However, attempting the

export

goal with the

--no-pantsd

argument also results in failure on my system. pantsbuild/pants
