Jenkins hangs after adding all extensions

Question

Jenkins hangs after adding all extensions

jenkins hangs on startup.

tail -10f / var / log / jenkins / jenkins.log

java -version

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

jenkins version ==> 2.60

Browser error:

Please wait while Jenkins is getting ready to work...

Your browser will reload automatically when Jenkins is ready

Tried:

1) restart jenkins and server
2) Changing the java version
3) Removed all jobs, etc

Celebrating works. Thank you in advance.

Have a similar issue filled here JENKINS-36931

To see what Jenkins does during startup, especially when a freeze occurs, follow these instructions:

" Getting a thread dump "

With this thread dump, you can at least know where Jenkins is stopping and what he is doing.

I seem to have the same problem starting today. After the "INFO: Augmented all extensions" message, several "missing symbolic links" are reported. - too many levels of symbolic links. it ends., Jenkins never shows up: "Wait while Jenkins gets ready to go."

UPDATE: WORKAROUND: disable fstrigger plugin.

$ touch /var/lib/jenkins/plugins/fstrigger.jpi.disabled
$ systemctl restart jenkins

I tried to restore the old jenkins config from backups but it didn't work. I looked at the recent work changes and found that removing some new jobs allowed jenkins to start. When Jenkins was unable to start lsof -p pid, it showed that he was slowly scanning the filetype that fstrigger was meant to look at. Disabling fstrigger allowed jenkins to start with a new job configuration.

So. I think my problem is a bug in fstrigger on startup. I think the error is because fstrigger is controlling a directory with a large structure underneath (perhaps recursive symlinks linking internal ones to the dir structure (log messages)).

jstack threadDump looks useless? To me.

but here is what I see anyway: ...

$ jstack 5670
5670: Unable to open socket file: target process not responding or HotSpot VM not loaded
The -F option can be used when the target process is not responding
$ jstack -F 5670
