出てくるエラーは2種類くらい
[Mon Feb 16 11:54:15 2009] [error] [client xxxx] Unable to PUT new contents for xxx [403, #0] [Mon Feb 16 11:54:15 2009] [error] [client xxxx] Could not prepare to write the file [500, #160012] [Mon Feb 16 11:54:15 2009] [error] [client xxxx] Cannot write to the prototype revision file of transaction '2-1' because a previous representation is currently being written by this process [500, #160012]
小規模なプロジェクトで問題は出たことがないのでパーミッション等の問題ではない気がする。扱えるデータのサイズ制限などがあるんだろうか?
[追記]
メモリが足りないんじゃないの?という指摘
