Dockers get disconnected when i do git fetch -p

[chencho m-a]

Hi all, 

I am facing an issue that is driving me crazy and I am going to ask here to see if someone can shed some light.

I have three jenkins clusters with a master per cluster and several builders. Each builder is triggering dockers to do certain tasks. I am using  jenkins lts and latest docker-plugin (i have tested several plugin versions with no luck). The problem is that from time to time I am getting this error:

[2022-02-09T00:26:02.052Z] git fetch -p

[2022-02-09T00:26:08.790Z] Cannot contact build-server-16-quickenv-005qxxrip1351: hudson.remoting.ChannelClosedException: Channel "hudson.remoting.Channel@58489cec:build-server-16-quickenv-005qxxrip1351": Remote call on build-server-16-quickenv-005qxxrip1351 failed. The channel is closing down or has closed down

[2022-02-09T06:54:03.365Z] Could not connect to build-server-16-quickenv-005qxxrip1351 to send interrupt signal to process

After this error, docker gets unresponsive from jenkins (but alive in the builder with another port, seems like docker socket has dead and reconnected in other port), and the jobs never ends waiting for a reconnection.

Any idea?
