Out of memory in diff
Closed, ResolvedPublic


Author: jayden54

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."

Don't know if this helps, but here's another example where only one character
was changed:

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?
