Re: [qmailtoaster] Re: segmentation fault

Sun, 10 Feb 2013 21:47:08 -0800

OK, I tried (somewhat foolishly) to re compile vpopmail from source. While it worked when I tried to add a domain. Unfortunately it borked my existing installation and did not play nicely with vqadmin. I was able to run newmodel and get it all back working, but the segmentation fault still exists. I am beginning t think this is a permission issue, but don't know where to start. Is there a list or can somebody give me a permission list for the vpopmail directory? 

Thanks,

CJ

Maybe something is wrong with your vpopmail table for that domain (dom_89)? 
Unless of course the domain is always another one.

Looks like it crashes right after receiving the results from the DB.
Run strace -f -s1024 to see more data.

I'd guess it might help to run gdb as well but I'd have to look up how
to use it exactly - it might help better.

Cheers,

Try recompiling it. Maybe a library got updated?

Already did to no avail.

Also strace or gdb might help to figure out why it crashes.

I don't know.
Are you running the latest vpopmail-toaster package? If so, I'd ask
about this on the vpopmail users list (mailto:[email protected]).

Yes I am.  Any other way to add users?

Vqadmin.

Doesn't work either Internal Server Error
