Hi, I don't know in which forum to report a freeze of RapidMiner. Therefore Developer.
I was using REGEX using the operator Replace on Attribute using REGEX.
I was trying to remove CSS like tags from a text.
RapidMinder Studio freezes after i added the ( and the ) in the above REGEX string.
The REGEX with ( and ) might look like a REGEX error but that wasn't indicated in the field. It just freezes. Tried it a few times but same freeze. Using v7.5003 on OSX with 32GB.
Btw: the "Recover Process" functionality works great! Back to where I was before adding the ( and ).
did you have a look at rapidminer-studio.log located at $USER/.RapidMiner/ ? This should indicate if this is a java out of memory or an regex error.
