Backup Task Crashing - Signal SIGABRT Error

[Felipe.rubilar]

Dear Cloudron Support Team,

I am experiencing a recurring issue with the backup tasks on my Cloudron instance. The backup task for the mail application is consistently crashing, and I am unable to determine the cause or find a solution.

Details:

• Error Log Excerpt:

Current Configuration:

• Memory Limit: 2 GiB
• Upload Part Size: 128 MiB

Issue:

I have not made any changes to the default configuration settings. The backup process crashes with a SIGABRT signal, indicating a critical error that the process could not handle.

Request:

Could you please assist me in diagnosing and resolving this issue? I would like to know the specific changes or configurations I should apply to prevent this problem from recurring and to ensure the stability of my Cloudron instance.

Thank you for your support.

Best regards

Can you check the system logs for around the time-frame when a backup crashes for indications if the system ran out of memory? There was another issue when SIGABRT was triggered https://forum.cloudron.io/topic/1720/backup-fails-task-475-crashed-with-code-null-and-signal-sigabrt which was also memory related.

Hi Nebulon,
Thank you for your assistance regarding the backup issue for the mail application. Based on your suggestion and the error logs, I have decided to increase the memory limit for the backup process to 4.5 GiB.

Here is the updated configuration:

Memory Limit: 4.5 GiB
Upload Part Size: 128 MiB

I will monitor the backup process after this change to see if it resolves the issue. I have attached a screenshot of the updated settings for your reference.

If the problem persists, I will provide additional logs and system metrics for further analysis.

Thank you for your support.

Best regards,
Felipe Rubilar
