Subject: git hangs on pthread_join
Message-ID: <20130523130143.GA6376@pomac.netswarm.net>

Hi,

I'm running a rather special configuration, basically i have a gerrit
server pushing
git data over openvpn connections (company regulations n' stuff)...

git 1.8.2.1 is started by xinetd
...
        port            = 9418
        socket_type     = stream
        wait            = no
        user            = gerrit2
        server          = /usr/bin/git
        server_args     =  daemon --inetd --syslog --export-all
--enable=receive-pack --init-timeout=3 --timeout=180 --base-path=<path>
...
        nice            = 10
        per_source      = UNLIMITED
        instances       = UNLIMITED
        flags           = KEEPALIVE NODELAY
---

Keepalive and nodelay has been added post fact, the same goes for the
timeouts.

I have found "git receive-pack"s that has been running for days/weeks
without terminating....

Attaching gdb and doing a trace results in:
#0  0x0000003261207b35 in pthread_join () from /lib64/libpthread.so.0
#1  0x00000000004ce58b in finish_async ()
#2  0x000000000045744b in cmd_receive_pack ()
#3  0x0000000000404851 in handle_internal_command ()
#4  0x0000000000404c9d in main ()
(sorry don't have any debug data for the binary packages apparenlty (rpms
was
built from the official source))

(RHEL 5 machine with glibc 2.5-65.el5_7.1)

Anyone that has any clues about what could be going wrong?
