Segmentation Fault With V5.2

[Amir]

Hi,

I seem to get Segmentation fault with v5.2 when i run it on my desktop. It used to happen with FC5 so I gave up on it. Recently I upgraded to FC6 and still i get seg faults. I've also tried to run it on my other box that runs RHEL3 and it seg faults there too.

I I run without arguments its displays usage. Only If i give it the XML does it barf 🙁

Code:

192.168.0.76
admin password 3306 live_ocs

newsql0
admin password 3306 live_ocs

I've changed the password to “password” in this post for obvious reasons. The log file is created but its 0 bytes 🙁

password is mixture of letters and numbers and “)” and “(” characters.

Please find attached strace.log.

Not reproduceable here. Testing includes Fedora3, Fedora5, RHEL4 and SuSE10.

I just tried passwords like '123()abc' and similar.

We will need a complete test case or temporary access to your server.

Create a ticket if you have some details you do not want to reveal here.

Unfortunatley the database servers are behind a firewall so I cant give you access. I'd be happy to run any testcase or anyting else you want me to run against the servers. I have root access to the server so can run any commands against the server.

FWIW one server (src) is 4.0.20 and the other is 5.X (destination).

Thanks for the PM…

So is there anything else at all I can do to find out whats wrong?, how can I make a “ticket”?.. Can I run the agent in debug mode to see what its not happy about?

Tried to run the app under gdb, but it just sits there (and does nothing) ?

OK .. reproduced now.

I can copy the text from your 'Code box' here and change the details and get the segmentation fault on Fedora3 and SuSE10. If I build a similar jobfile with the wizard on Windows and copy that file to Linux I do not.

Password does not matter. It is reproducable with any password.

We will have to look detailed into this tomorrow.

Thank you VERY much! 🙂

First observations is that if you add tags for each connection it will work. However omitting a tag should be OK, so this must be considered a bug.

Enter the tags like:

Code:

localhost
root **** 3306 [default]
test2

localhost
root **** 3306 [default]
test3

Added element and its working fine now.

It should now (version 5.21) also work on LINUX without the tag.

Can you confirm?
