Hi,
did you set the limits in correct user context (see
/etc/security/limits.conf)? No sorry, I'm not an expert in this.
Regarding the crash: I do see the sig 11 below. Did you try to hit
CTRL-C (as described) and generate a backtrace then?
Thanks!
Hilmar
coredump did not generated. Have tried to use:
|ulimit -c unlimited|
with no effects (have checked / and /root directories to find coredump)
Then have installed proftpd debug symbols and gdb and start proftpd
debugging
root@sim-ng-data /run # gdb proftpd

Is a core dump generated for the crash? If not, don't care for now.
The URL [1] describes some basic steps how to generated a back trace for
debugging. Please follow them as far as possible, in case of questions
please call back. The section "Installing the debugging symbols" won't
work as described; our debug symbols are not in archive yet. However
I've uploaded the appropriate dbgsym packages to the location where you
got the proftpd package, please install them from there.
