SVN Commit Error (couldn't perform atomic operation)

In my case, it was because the partition that svn had been installed in, was full.

Make sure there is space on your SVN Server's hard drive partition!

I noticed the same behavior. Wait a couple minutes then it worked. But that didn't always fix the problem. After looking at our SVN server we found that one of the partitions (the one that the server was on) was chalk full.

I had our IT guy clean up some of the space and everything worked nice and slick after that.

Weird, it started working fine, after about 15 mins.

I did not do anything.
