My Support Case is #1193443 - "KSS 9.6.1 was stopped, when it received a syslog by TCP."
I got the Buddy Drop 33351 that fixes this problem.
After applied this BD, KSS 9.6.1(9.6.1.28) can received TCP logs without error.
SolarWinds says that I can not provide this BD to another user.
Please ask SolarWinds technical support how to get this BD33351.
Regards,
