Beware of a bug of WEBrick


Hi all,

I’m not sure that here is the right place to post(so sorry if it is
but it seems that WEBrick is not being maintained any more.

I found that WEBricks freezes with 100% of CPU usage whenever it takes a
POST message of invalid format(multipart/form-data with invalid
boundary). Then the server is able to process any other requests no

Be careful if you’re doing some serious things with script/server.
