PROBLEM SOLVED

Hello,

system:
CentOS 5.1 64-bit
Kernel: Linux 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:37:38 EST 2008 x86_64 x86_64 x86_64 GNU/Linux
Mem: 4Gb
Directadmin 1.31.5

When I run a reseller backup, I get the following error in System Messages:

May 7 23:32:02 host kernel: dataskq[6421]: segfault at 0000000000000001 rip 0000003f2c866280 rsp 00007fff73052248 error 4

DA System.log
2008:05:07-23:32:01: Running Backup: type=reseller owner=ownresel id=(null)

Someone?

TIA,
Fossie

Solution:
How the problem was created
First I made backups of the upload scripts
I copied ftp_upload.php.old to ftp_upload.php
didn't work
I copied the backup again to ftp_upload.php
didn't work, why?

Due copy process, forgot to change ownership of the files
chowned to diradmin:diradmin and problem went away

DirectAdmin was not able to execute the ftp_upload with root:root as owner!

Backups are uploaded with the new ncftpput script!

Thx anyone for helping, trying to help.

This might be due to memory hardware issue.

Maybe this is the same issue?

I think there is nothing wrong with the memory, it's when the backup runs from the control panel, it gives this error, when I run the

ncftpput -t 25 -m -u -p host rem_path local_path

in ssh, the file is transfered normally.

If it's a memory issue, how can I test it on a live production server?

 

[tanfwc]

You need to ask the NOC to run memtest on your server to test for memory issues

I installed Dell's diagnostics tool and ran the memory module test:

./pediags memory --run time=45 fmt=tbl

Output seems to be ok: should I run it for longer time? (45mins seems to be less, LOL)

I only get this error when running reseller backup and store it on remote ftp server.

Currently workaround:
reseller backup to local disk, script to copy file to remote ftp host and added it to cron half hour after the reseller backup script runs.

Strange issue, is there some other way to test, see what dataskq does (commands that run when reseller backup has to run?

TIA,
Fossie

I got the same error today when doing backup from a server and restore on a remote server. I tried both Admin backup/transfer feature in DA, and backup to local then ftp to remote host, then restore. No success.

Tried with stable and pre-release versions without success either. Waiting for John's reply. Any other work around please?

John has a fix for this. Downloaded the latest package and it's working well now.
