c.s.h.p.g.t.GerritProjectListUpdater#tryLoadProjectList: Not connected to Gerrit, waiting for 64 secon d(s)

Hello,

our Jenkins "all of a sudden" takes nearly 3 minutes to start. (Ok, I guess, some of you are now laughing)

I never stopped the time exactely in the past, but it had been significantly less. (I would guess something like 1 minute)

Looking at the log, I see:

So it seems, it needs two minutes (out of three !) to connect to Gerrit.
(Which would explain the difference I see)

I didn't see Gerrit problems in operation.

How can I get more details to debug the reason ?
Any ideas to improve this ?

Regards

Martin

Update:
Two things happened over the weekend:

- Our Gerrit HW got updated

- I just updated the used JDK from  JDK 8 (jdk8u265-b01) to JDK11 (jdk-11.0.9.1+1)

It started up much, much faster. In the logs I (just) found:
"Not connected to Gerrit, waiting for X second(s)", with X=1,2,4

• Pure luck ?
• Gerrit update during the weekend helping (a lot) ?
• JDK update helping ?
