End of May this was announced (From https://boinc.berkeley.edu/project_news.php):
[LODA] Upcoming maintenance

We will go into a planned maintenance in the next few weeks. In the first phase, we will stop creating new workunits and wait until the majority of in-progress work is finished. During the maintenance, the BOINC server will be offline. We will post updates at https://loda-lang.org/. Thanks for your contributions and patience!

Back to running now.
In summary the message:
The operating system cannot run (null).
(0xc3) - exit code 195 (0xc3)</message>

Seems to be down to the PROJECT_DIR environment being set wrong for LODA.

  • A project reset corrects this issue.
  • After the reset you need to rename zlib1-260314-windows-x86.dll to zlib1.dll.

All my tasks are now failing, same error as above. Only difference is the failure occurs within a few seconds.

Found the link to my LODA logfiles: https://boinc.loda-lang.org/loda/logs.php

The output for one task is below:

PROJECT_DIR is being set incorrectly, along with anything that references ProgramData, they should refer to my D: drive. Any suggestions on how to change it?

In the meantime I'll reset the project.

Is it an issue relating to the suspending and resuming of tasks?
6) Questions and Answers : Bugs : All tasks resulting in computation error (Message 1087)
Posted 23 Mar 2026 by treaclepumpkin
Post:

When it happens to me that the application crashes, I reset the project, then I update it and the problem gets fixed. It does not fix itself without manual intervention; once the application crashes on a WU, all subsequent WUs will go wrong until, in my case, I reset the project and start over, and then everything works, until the next time it happens again.


Yes have tried that.

Post:
Tried one of the earlier fixes, https://boinc.loda-lang.org/loda/forum_thread.php?id=136

It seems like the loda-260125-windows-x86.exe executable file it looking for a DLLs called libcurl.dll and zlib1.dll.

To fix if I did the following:

    1) cd to BOINC project directory(C:\ProgramData\BOINC\projects\boinc.loda-lang.org_loda)
    2) Copy libcurl-260125-windows-x86.dll to libcurl.dll
    3) Copy zlib1-260125-windows-x86.dll to zlib1.dll


After making these changes I pulled down new tasks and everything starting working normally.



Modified the copy to take into account v260314 naming and created the new files. Hasn't worked so it's not that.

"LODA v2601.25 windows_x86_64" version of the app still generates the error: "The operating system cannot run (null)."
Only "good" thing is that the tasks take a few seconds to fail.

Posted 16 Dec 2025 by treaclepumpkin
Post:
The last week or so I've been getting the "exceeded elapsed time limit" on tasks. I have aborted some tasks and then reset the project to see if if that helps but no I'm still getting the error. This is on two Windows machines running 10 & 11, using the 251201 version of the app.

Links to some tasks that have the error but were returned before exceeding the deadline date:
https://boinc.loda-lang.org/loda/result.php?resultid=17597374
https://boinc.loda-lang.org/loda/result.php?resultid=17575923

I have had three tasks complete successfully over the same period.
Anyone else experiencing this or know of a possible solution?

Looks like you've just signed up to LODA and LHC and only downloaded tasks this morning, which I think means that git is installed correctly. It will be at least a day before you start receiving credit for any completed tasks.

Okay the update following the software resets and re-installs I carried out, yesterday.
Because of all the errors I've been generating BOINC, not LODA, is restricting my PC to only one LODA task a day, hence this message in the logfile:
This computer has finished a daily quota of 1 tasks
If I start returning completed tasks for LODA then the quota will be gradually raised. Anyway the one task I got today failed with the same error, it did take over a minute to do so rather than just a few seconds, but that isn't pertinent to the issue.
So the last part of the logfile, for today's failed task, is:
Updating files: 100% (104467/104467), done.
curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
2022-10-28 07:19:13|INFO |curl -fsSLo "D:\ProgramData\BOINC/projects/boinc.loda-lang.org_loda\miners.default.json" https://raw.githubusercontent.com/loda-lang/loda-cpp/main/miners.default.json
2022-10-28 07:19:13|ERROR|Error fetching https://raw.githubusercontent.com/loda-lang/loda-cpp/main/miners.default.json


The only information I can find round this error is that adding
-ssl-no-revoke
to the curl parameters would probably stop the error
The revocation function was unable to check revocation for the certificate
being generated and so may allow the fetch of the JSON data to succeed. But that's something for the LODA devs to look into, unless someone knows if that can be changed locally? Some override in the project preferences maybe?
I'll leave the project running but reduce the priority, not that I'll be doing much with one task a day anyway.

Cheers

Thanks @Conan for the reply,
As you say I already have curl on Windows 10.
I've reset the project, uninstalled git - rebooted. Then installed git,using the defaults this time, rebooted and restarted the project. I can't get any project files today, as I've exceeded a limit so will pick up later.

The logs for the task say:
2022-10-26 08:17:01|ERROR|Error fetching https://raw.githubusercontent.com/loda-lang/loda-cpp/main/miners.default.json


I've verified that the PC can access that JSON. So see what happens tomorrow.

I've been having a similar problem the last couple of weeks, not all tasks have been failing but the failure rate seems to be increasing.
So, I'm using Windows 10, found that the System temp area (C:\WINDOWS\TEMP) wasn't writable but the User area (C:\Users\account\AppData\Local\Temp) was writable. BOINC runs, on my machine, as the logged in account so should be using the User temp area, I reset the permissions on the System area anyway.
Restarted and still got the same issues, i.e. tasks failing within a few seconds with "exit code 195", see this task .
I recall seeing a post about needing to install git, something I do use already, for LODA. So I checked that out. Seems my version wasn't the most recent but also required a re-install, so I've done that.

Restarted and started running tasks since then and I still get the same error, tasks do seem to take longer to fail now. I'm running with the following:

  • BOINC: 7.20.2 (x64)
  • Windows: 10.0.19045
  • CPU: Core i5-12600KF
  • GPU: Radeon RX580 (22.5.1 drivers)


Anyone have any ideas please?
