Segmentation fault

[elbarto]

I'm getting a segmentation fault when I try to run directadmin. It was working fine until a couple of hours ago. It stopped working. I logged in to my server and saw it throws a segfault.

$ /usr/local/directadmin/directadmin d
Segmentation fault

I tryied to run gdb but got this error:

[root@myserver directadmin]# gdb directadmin

Can you help me to fix it? I need to fix it ASAP, because I have lots of clients complaining.

Thanks in advance

What did you do between the time it was working and the time it stopped working?

I personally did nothing, but I think there was some update during the night.
I have some errors on directadmin's error.log.
I changed sensible information for security reasons:

2010:01:05-14:02:55: Socket write error: fd is connected to a pipe or socket whose reading end is closed.  When this  happens the writing process will also receive a SIG_PIPE signal.  (Thus, the write return value is seen only if  the program catches, blocks or ignores this signal.)

The IPs which I replaced by "1.1.1.1" and "2.2.2.2", I don't know them. The IP "3.3.3.3" is my server's IP address. Before these lines, I see similar errors with "Error reading from", but the IP change. I have some with other IPs of the same network as 1.1.1.1, i.e: 1.1.1.2 and 1.1.1.3. I tried to ping all those IPs but they do not respond. I'm not sure if this is an important error or if I should look somewhere else.

I'll try to update manually and let you know.

Search on google:

Variety of answers.

Thanks floyd. It turns out that the problem was a connection error during the update. I did a manual update (http://help.directadmin.com/item.php?id=29) and it's working now.
Thanks!
