Last updated on FEBRUARY 05, 2020

Applies to:

Oracle Database - Enterprise Edition - Version 18.3.0.0.0 and later
Information in this document applies to any platform.

Symptoms

The following error occurs in the alert log:

ORA-07445: exception encountered: core dump [kmm_network_ftcbk()+558] [SIGSEGV] [ADDR:0x0] [PC:0xABC73EE] [SI_KERNEL(general_protection)] []

 

The Current SQL Statement in the associated incident trace file shows a query (SELECT) on gv$listener_network or on its base table X$KMMNV.

 

The Call Stack Trace in the same incident trace file shows:

kmm_network_ftcbk
 <- qerfxFetch <- qerandvFetch <- qergsFetch <- opifch2 <- kpoal8
  <- opiodr <- kpoodrc <- rpiswu2 <- kpoodr <- upirtrc
   <- kpurcsc <- kpufch0 <- kpufch <- qksanExecSql <- qksanAnalyzeSqlConC
    <- qksanAnalyzeSql <- qksanAnalyzeSegSql <- kestsGatherSqlStati <- stics <- kestsProcessSql
     <- kestsProcessSqlCall <- out <- spefcmpa <- out <- spefmccallstd
      <- peftrusted <- psdexsp <- rpiswu2 <- kxe_push_env_intern <- al_pp_
       <- kkx_push_env_for_IC <- D_for_new_session <- psdextp <- D_for_new_session <- pefccal

         <- plsql_run <- peidxr_run <- peidxexe <- kkxdexe <- kkxmpexe

Notice that the stack is likely to include:  kmm_network_ftcbk qerfxFetch qerandvFetch qergsFetch
