Confluence backup exception

Ajay Gupta
Ajay Gupta May 21, 2019

I installed confluence server 6.15.4, few handfull spaces. Things went well, and tried taking full backup, which fails.

With attachment, it fails, with error: 

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /confluence/admin/dobackup.action.

Reason: Error reading from remote server

The XMLExport is generated and looks valid, as was able to import in development server.

-rw-r----- 1 user-x user-x  1.6G 2019-05-21 15:52 xmlexport-20190521-155014-1.zip

If I disable attachment, it works. with attachment, size is only 1.6 GB, and without attachments - 1.2 MB. Issue is not with downloads, as backup is in temp folder, and it takes about 60 sec for exception. Seems some timeout value need to be changed.

Need this as pre-requirement for upgrades.

thanks.

There might be multiple reasons for the error.Regarding timeout you can check proxy(eg:apache) timeout and the tomcat timeout in server.xml.

Did not work, I increased org.apache.catalina.valves.StuckThreadDetectionValve=300 and org.apache.catalina.valves.StuckThreadDetectionValve=300. 

The exception from logs went away, but, still see exception on Web. 

I was also monitoring atlassian/application-data/confluence/temp, and ZIP was working long after exception and successfully created xmlexport-20190522-073000-3.zip.

I was able to find reference which pointed issue in given version of confluence. I upgraded to next point release and working since then. My backup size are about 3.6 GB (zip) and include attachments.

Hope it helps.
