[Savannah-help-public] git repository doesn't accepts pushes anymore

[Francesco Salvestrini]

Hi

In the last few days the git repository for 'sitetool' project
(https://savannah.nongnu.org/projects/sitetool) on savannah stopped accepting
git 'pushes'.

When I try to push the latest changes git starts sending updates but  the
procedure hangs and gets interrupted by a timeout.

In order to investigate the problem I've created a simple on-liner
script 'ssh-debug-wrapper' like the following one:

ssh -v -v -v $@

Then the following command:

GIT_SSH="./ssh_debug_wrapper" git push

Outputs what follows:

address@hidden:~/Sviluppo/sitetool/sitetool$ GIT_SSH="./ssh-debug-wrapper"
git push

The repository worked without problems since the it was created.

It seems to me a server-side error but I have no clues ... any hint
welcomed :-)
