I saw the same today on a customer server after he tryed to update Roundcube to latest version using CB plugin.

I dont know actually if it is related to that, i've just killed those "tr" processes and the server load went fine (and those processess didnt restart).

Did you update something using CB plugin? If yes it may be a CB plugin related process, otherwise i think a further investigation will be needed on my customer server aswell actually.

Regards

I did update RC on customer server using ssh, i just wrote to Martynas to ask him if the CB plugin is somehow using that command so far.

I also did check crontabs but apparently that command isn't used on crontabs

Issue affected CustomBuild plugin only. It has been fixed in CB 2.0 rev. 1388. Thank you for the report! :)
