Bug#275301: ssh2 freeze in select() when used as a transport medium for cvs or scp
Package: ssh2
Version: 2.0.13-7
Severity: important
When i do a scp from using this computer or when i use cvs over ssh,
at some time or another it freeze during process and i have to ctrl-C.
I did install the lic6-gdb package, plugged gdb in the process after the
freeze and did a backtrace (see below). As you can see, ssh is stuck in
select() function. Could not find any informations on this.
This is quite a problem as it render cvs tool over ssh useless :/ (it
can never do a complete checkout).
backtrace after freeze in a cvs process:
