Backup with container failes with "13 segmentatin fault" and "msg.sock: Permission denied"

[whentotrade]

The backup fails with the following information in the debug log.

Any idea?

you got a SIGSEGV, isn't that interesting?

I see two (possibly distinct) issues:

• mysqldump coredumped. Does it say why? What are the next lines?
• samba has some sort of issue

The rest of it just follows from that error / those errors.

What is your backup target? Can you scrub the rest of the logs and post them, maybe to a gist?

This error happened and when I debugged I found out there was space in front of password so it read as -p mysqlDBPa$$W0rd instead of -pmysqlDBPa$$W0rd.

In my case, I didn't use samba but file system storage. I am adding this information under this issue as we get 'Segmentation fault' in this case too and might help someone.

I think the fix is to trim password and all env variables to avoid such issues

[deitch]

Wow. Who would think that a space after the password would cause a sigsegv?

Yes, that is the fix. Let's at least start with the password. Should be easy enough. Want to open a PR on it?

[tanmally]

Since this issue is not related to samba but file system storage I have created another issue and happy to contribute a fix via PR and shall link it to the new issue #142
