New 503 Error

[theRKF]

I'm using a tool in our CMS dashboard that I've used a thousand times (literally!!) to import an XML file by uploading from my PC. As of this morning, I'm immediately greeted with the famed 503 error.

I do have the graceful restart option enabled, and I've tried a few restarts myself without success.

I would prefer to not have to recompile PHP (as that seems to be the prevailing wisdom on 503s) since PHP was originally compiled by LiteSpeed support in a special configuration.

Any other ieas? I don't see any nuggets of wisdom in the log files, except for the fact that the error occurred.
