Never had this issue.
Have you tried the latest version 0.8.6?
Topic: "Failed to write undo data" on Bitcoin QT 0.8.0 on OSX 10.7.2 (Read 1446 times)
same problem here. Let me know if there's a resolution.
Just last night my Bitcoin QT client started getting all wonky on me. Luckily I have backed up my wallet.dat file, so I'm not freaking out, but this is becoming a pain in the ass. I'm somewhat technically literate, but all the Googling I have done to figure out what is going on is way over my head.
I have managed to look at the debug file in Users/Library/Application Support/Bitcoin, and have identified the trouble area, but I have no idea what it means or how to fix it.

ERROR: CBlockUndo::WriteToDisk() : OpenUndoFile failed
*** Failed to write undo data
Some of the reading I have done says that it could have something to do with an open files limitation on OSX, but I don't see anything in my system log file (/var/log/system.log) that says "too many files".
My first thought would be to update the Bitcoin QT client, but I am nervous about updating. I don't want to make the problem worse.
Edit: Had mistaken Bitcoin QT version number in subject title.
