I have recently upgraded to jenkins 2.89.4 from 2.46.2. Prevoiusly it was running with jdk7 now it is jdk8.

Upgrade went well, everything looks working but when I try to change the configuration of any job it gives below error page with HTTP 400 response:

Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.
Cookie
/n
Apache/2.2.15 (CentOS) Server at node0.morado.com Port 443

I did delete the cookies and refreshed the page. It get loaded with the desired contents but again within a minute it gives the same HTTP 400 response as above.

I have referred the existing JIRA JENKINS-25046. But that solves the issue temporarily.

Does anybody know what is wrong here?
