Jenkins master 1.651.2 running in JBoss EAP 6.4.7 on Java 8 on Linux (Centos 6.7).
Slave is Windows Server 2008r2 running in AWS, launched via the ec2 plugin.
We have a use case where we frequently dynamically create slaves to run certain jobs.
We've noticed that the first time a job is run on a new slave node, the "Loading node environment variables." step takes a very long time (~4-5 minutes).
Using the timestamper plugin, we obtained the following logs:
First run:
20:06:54 Started by user Daniel 20:06:54 [EnvInject] - Loading node environment variables. 20:11:26 [EnvInject] - Preparing an environment for the build. 20:11:26 [EnvInject] - Keeping Jenkins system variables. 20:11:30 [EnvInject] - Keeping Jenkins build variables. 20:11:57 [EnvInject] - Injecting as environment variables the properties content 20:11:57 TESTCOMPLETE_PLUGIN_DEBUG=true 20:11:57 20:11:57 [EnvInject] - Variables injected successfully. 20:11:57 [EnvInject] - Injecting contributions. 20:11:57 Building remotely on Windows Server 2008 TestComplete (i-0a5791d0) (testcomplete) in workspace c:\jenkins\workspace\testcomplete_Create_VM
Second run on same slave:
20:22:18 Started by user Daniel 20:22:18 [EnvInject] - Loading node environment variables. 20:22:20 [EnvInject] - Preparing an environment for the build. 20:22:20 [EnvInject] - Keeping Jenkins system variables. 20:22:20 [EnvInject] - Keeping Jenkins build variables. 20:22:21 [EnvInject] - Injecting as environment variables the properties content 20:22:21 TESTCOMPLETE_PLUGIN_DEBUG=true 20:22:21 20:22:21 [EnvInject] - Variables injected successfully. 20:22:21 [EnvInject] - Injecting contributions. 20:22:21 Building remotely on Windows Server 2008 TestComplete (i-0a5791d0) (testcomplete) in workspace c:\jenkins\workspace\testcomplete_Create_VM
There's another ~30s delay in "Keeping Jenkins build variables.", which also seems long a long time.
There doesn't appear to be any CPU contention or anything of that nature going on that I can see.
Any ideas what could be causing the delay?
How would you recommend debugging it?
