100% agree, and hopefully no one reads into this email thread any sort of recommendation to incorporate haveged into their environments. I've created NIFI-13595, for someone to have a look at this test. Thanks for the suggestion about the alternate method, hopefully that will help. Also, thank you for your patience working through the issue! For weird problems like this, an environment where a problem can be reliably reproduced is very helpful.
