Segmentation fault (core dumped)

2. 'docker start -ai otter' (or "docker rm otter; docker run -it --name=otter ...)

• Segmentation fault (core dumped)

3. Workaround: (before 'docker start') clear content of folder "Temp path" (/tmp/otter) on the last server (or otherwise - on all servers)

4. Quick repeated crash:

• [2] Creating a new server with incorrect parameters (workaround: delete record from table Servers);
• (or) [3] Changing the account ("Credentials" of server) with the same "Temp path" (workaround: separated /tmp/otter/username);
• (or) [4] Run script with any typo (workaround: delete record from table RaftItems).

Hello;

Thanks for all the detailed information, we'll definitely investigate what could be causing a segfault. This definitely shouldn't be the case...

is anything logged in Admin > Diagnostic Center?

Thanks.

Hello, Alana

In DiagnosticCenter\LogMessages only:
Error scanning PowerShell agent: MI_RESULT_ACCESS_DENIED ServerCheckerRunner 09/28/2021 03:29:38

...

here bold - last message before crash.

I sended some details with tiket '[EDO-7968]':

1. logs_otter*.txt - last result of command 'docker logs otter';
2. LogMessages.csv - sql-export of table 'LogMessages'.

I can collect data what you say.

Best wishes,
Igor

Hi Igor,

Thanks for the help in tracking this down. We've now fixed this in an internal build (logged as OT-428) . The fix will be in Otter v3.0.12, scheduled for release on October 8.

If you'd like to test a prerelease build, you can pull the proget.inedo.com/productimages/inedo/otter:3.0.12-ci.1 image, which already contains the fix.
