Server our of memory error when syncing large file (error log attached)

[MTRichards]

Syncing large files doesn't work for me, and it seems to be a server issue. This is a reposted issue, also in the Mirall list as owncloud/client#19

The large (1.4GB) file uploads to ownCloud 4.5 via the 1.1.1 works client just fine (from windows client on windows 7) and I can see the file in the web client, but the same file will not be downloaded to the other desktop clients.

Tried 2 windows 7 machines, and 1 ubuntu 12.04 machine running the ownCloud client.

Same here:

2012/11/20 09:54:18 [error] 24224#0: _36138 FastCGI sent in stderr: "PHP message: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 781856768 bytes) in /var/www/owncloud.kaiser.me/public/3rdparty/Sabre/HTTP/Response.php on line 146" while reading response header from upstream, client: 80.190.141.50, server: owncloud.kaiser.me, request: "GET https://owncloud.kaiser.me/remote.php/webdav/clientsync/_***********.avi HTTP/1.1", upstream: "fastcgi://unix:/tmp/php5-fpm.sock:", host: "owncloud.kaiser.me"

Don't know if Sabre supports a streaming interface or if there are other DAV modules. The upload worked somehow...

Update: as noted in another ticket, "output_buffering = Off" solves the problem. Maybe this should be either avoided, or described in the installation process...

Which setting did you have before? On (=unlimited) or a specified buffer size?
