Could you once check the nifi-app.log to know which processor is causing the issue and
1.if issue is because of java heap space then increase the heap space in bootstrap.conf file to 8g or more(if you are having) then restart the nifi server.

java.arg.2=-Xms8g
java.arg.3=-Xmx8g

please follow this article for more details about the configs.

2.if this issue is causing my some specific processor(like invokehttp,scripted processors ..etc) then delete those specific processors in flow.xml.gz(1.take backup of flow.xml.gz 2.gunzip <flow.xml.gz> 3.vi flow.xml 4.delete the processor causing the issue and all connections to that processor 5.gzip <flow.xml>)
3.if you are not caring about your any of the processors in your NiFi instance and need NiFi UI back to normal then delete (or) rename the flow.xml.gz to some other name not as flow.xml.gz in conf directory then restart NiFi.

No processor is causing this issue, It is NiFi when having simultaneous HTTP requests gining this error
