atlassian-jira logs spammed with WARN 12 when running view server log files

[Dimitar Erinin]

Hello,

When trying to view server log files after upgrading to 5.5.5 I am getting equal to the number of lines I am trying to view of: 

2019-05-17 16:27:14,797 http-nio-8080-exec-26 WARN xxxx.xxxxx 841x2085839x1 1yg1czi xx.xxx.xxx.xx,0:0:0:0:0:0:0:1 /rest/scriptrunner/latest/user/exec/ [c.o.scriptrunner.runner.ScriptRunnerImpl] 12

Edit - Looks like this is the contents of the logs... There is a stuck process :(  
Ignore this :)
