[389-users] Re: Finding cause of 389ds sefault crash

Hi,

By any chance do you know if the crash (SIGSEV) dumped a core ?
In such case you may install debuginfo rpm and analyze (gdb) the reason of the crash.

I am not sure the crash is due to a DB corruption/breakage but clearly the crash will trigger a recovery.
Is the suffix (userRoot) replicated ? is it a supplier or a hub ?
I have the feeling it crashed while compacting the changelog. bdb_db_compact_one_db is possibly missing a test that the 'db' (changelog) exists before dereferencing it.

regards
thierry

Good afternoon    Our ns-slapd crashed earlier today, with a segfault in libback-ldbm.so  while the system was running a bdb_db_compact_one_db action.    Is there anyway to trackdown/diagnose what might have caused the  segfault? Some type of DB integrity check or something?    Nelson
