"A segmentation fault has occurred" error in Brute Force Monitor Page

[gokcer]

When I click to Brute Force Monitor button at the main page I get:

Program Error

Details

A segmentation fault has occurred
http://help.directadmin.com/item.php?id=185

Directadmin error log:

*** Segmentation fault *** Log::~Log : done : User: admin : XXX.XXX.XXX.XXX : /CMD_BRUTE_FORCE_MONITOR : sort1=-1 : (null)

and lots of:

Table::tblcomp((null), (null))

And the output of gdb:

#0 0x000000380fc79a14 in strncpy () from /lib64/libc.so.6

Can anyone help about this?

Check the error log or put directadmin into debug mode.

Check the error log or put directadmin into debug mode.

Debug mode output is already above

 

[gokcer]

Does "no answers" mean "this is a bug"?

 

[mr.applesauce]

why dont you email directadmin support and find out

 

[zEitEr]

Directadmin has its own debug system, that's output would help. So run directadmin in debug mode and post here its results.

Thank you zEitEr. here is the output (domain name and ip changed to xxx by me):

OK, I see, not that informative output it is. What if you temporary empty the file brute_log_entries.list and try again. Will this help you?

Yes, i tried that but it didn't solve the problem.

 

[zEitEr]

OK, I guess Directadmin Support would need to take a look at this thread. Will you provide us with information about your OS release name and its version?

 

[gokcer]

Problem gone away without doing anything Maybe the BFM log clearing rotation fixed it, I don't know.

Even so, thank you for your help zEitEr

Best Regards...

 

[zEitEr]

That's good.

Is it a Directadmin bug?

Had the same issue, purging / recreating

/usr/local/directadmin/data/admin/brute_log_entries.list

helped instantly.
