It might be worth having a bit more details on your configuration, since that resulting from test044 (which basically complies with the info you provided) doesn't even hit that line of code (because rs->sr_flags == 0). So there must be something in between that causes the entry to be freed. That could be slapo-dynlist in some cases, but also slapo-translucent, slapo-collect, slapo-rwm or slapo-valsort. I guess at this point you should share the conf, the data and the op that's causing trouble. p. p. Ing. Pierangelo Masarati OpenLDAP Core Team SysNet s.n.c.

(ITS#4802) refint mutex bug
by h.b.furuseth＠usit.uio.no 11 Jan '07

11 Jan '07

Full_Name: Hallvard B Furuseth Version: HEAD OS: Linux URL: Submission from: (NULL) (129.240.202.105) overlays/refint.c:refint_close() does refint_data *id = on->on_bi.bi_private; memset( id, 0, sizeof(*id)); which overwrites id->qmutex. Then refint_db_destroy() does ldap_pvt_thread_mutex_destroy( &id->qmutex ); which can fail. I don't know what the required lifetime for that mutex is - if refint_close() must preserve it, or if it can destroy it and set on->on_bi.bi_private = NULL (so refint_db_destroy will do nothing), or something else.
