Child died with signal 11
Is this the exact error message? Dovecot doesn't send this, so do you mean it's PAM subprocess that dies or dovecot-auth process itself? The complete error is: dovecot-auth: Feb 25 18:55:17 Error: PAM: Child process died dovecot-auth: Feb 25 18:55:18 Error: PAM: Child 2179 died with signal 11
So it's the pam process crashing.
Crashes are better debugged with gdb:
gdb /usr/local/libexec/dovecot/dovecot-auth (pid of dovecot-auth)
Enter "c" command to let it continue. Try logging in. gdb should show that it crashed now. Enter "bt" command and send me the result. As I'm new to gdb, I'm stuck here. dovecot-auth does not crash so I'm not back to the gdb prompt. How do I get any output (CTRL-C does not work.)?
If it crashes inside pam_ldap handler, it's a bug in it. At least pam_ldap is fine with man other services (login,smtp auth, ssh).
Thanks for your time.
