ListenSyslog - Apache NiFi (Buffer size Error)


Hi everyone,

I am using "ListenSyslog" processor and I faced the below error:

ListenSyslog Attempted to set Socket Buffer Size to 314572800 bytes but could only set to 212992bytes. You may want to consider changing the Operating System's maximum receive buffer
