this error happens sometimes

Thanks for the report - could you provide the following info?

• What OS you're using
• What version of ParPar you're running
• How did you obtain/build ParPar? Pre-built binaries, or installed yourself via NPM/Git?
• If you're not using a pre-built binary, what version of NodeJS are you running?
• A sample command which produces that error? Also, it'd be helpful if you could post the full output of the run.
• When does the error occur? Immediately after running the command? Once the whole process is finished?

NAME="Ubuntu" VERSION="20.04.6 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian

Thanks for the extra info!
Unfortunately, I can't reproduce your issue, and I'm not able to see any obvious candidate as to why it's occurring.

• Can I assume this is the static AMD64 build?
• Can you do a run without the -q flag so that the output is shown?
• Can you try installing this via NPM or Git instead of the pre-built binary, and see if the issue crops up?
• Only if you know how: could you run this inside GDB and print out handle->flags and handle->type when the assertion hits? This may not work with the pre-built binary, so only try this with your own build from the above step

[mohitjoshi155]

yes static build I think this error is only happening for small files like 100 to 300 mb files that also for some random files I noticed that increasing the slices size and reducing memory helps with this error to some extent I have not encountered this error for big files yet seems very specific issue,not a big deal I am closing the issue for now if you dont mind

Thanks for replying Sir, appreciate your efforts

[animetosho]

Thanks for more info. I've been trying a bunch of things to try to find it, but haven't been successful getting anywhere.

Would you happen to be low on free memory perhaps?

Otherwise I'm interested to hear if anyone else is getting similar issues.

[animetosho]

By pure luck, I managed to encounter this. Unfortunately I can't get it to happen again, but I have a theory, so implemented a fix.

Are you able to try a build from the dev branch? Otherwise I might sort out a release with this fix.

[animetosho]

v0.4.3 released, which should hopefully fix this issue. If you try it out, please let me know how well it fares.
