It seems that the diff engine doesn't work when really large changes are made.
The following diff demonstrates this problem:
If you look at the diff it appears as if no changes at all have been made, but
in reality around 64,000 characters were removed. Obviously something is wrong
as a message is also displayed: "Out of memory in diff."
It's now occurring with small changes also:
Don't know if this helps, but here's another example where only one character
The changes are not really large. Those diffs would only require a few hundred
KB. The problem is probably that some servers (srv51, srv69, srv103) are
swapping and are probably experiencing transient out of memory conditions.

I can't reproduce this. This bug is very old and looks like sporadic server problems. WORKSFORME?
