swoog (192.168.50.11[192.168.50.11]) - ProFTPD terminating (signal 11)
Does it ring a bell ?
There is no sufficient information, perhaps you must up the debug
level (try -d 9). If you can't see the error, try to run it without
mod_ldap configuration (using your system users).
upping the debug level doesn't provide anything more (actually it
seems 5 is the maximum debug level)
working without ldap works fine
working with ldap+tls doesn't work because the ldap server can't speak
tls, but in that case proftpd doesn't die. It simply answers 'no such
user'.
If nothing works you can use a strace command (system call tracer) to
obtain more data. The most simple use is strace -p <proftpd_PID>
As proftpd spawns a new daemon for each incomming connection, I did an
strace -fn $proftpdpid, and here is what comes out when I try to
connect : (snipped the former lines as it's quite long)

And then the parrent process spawns some more lines before it stays
still waiting for a new connection.
The sig11 is clearly there, but I'm not a developper, so can someone
interpret this? Or is it still too scarse in informations? If more
info is needed, how can I provide it ?
I have tried to recompile debian's package with the latest release of
mod_ldap, but it displays the same behaviour.
Thanks for your help,
