[Pkg-openldap-devel] Bug#464024: Update: backtrace of dead consumer

[Ralph Rößner]

Hi,

after spending some time trying - without success - to reproduce my
problems with a test producer slapd, I switched my test consumer back to
the production producer and was able to capture another consumer SEGV.
This time my gdb was ready for it, so here is the backtrace:


0xb7c6f590 in pthread_join () from /lib/libpthread.so.0
(gdb) cont
Continuing.

The relevant syslog entries from the consumer machine show up the empty
csn again:

Note that this is on both ends of the connection package version
2.4.7-4, not -3 as in the original post.
