Symptoms

When either Shared Servers or Connection Pooling is enabled, the following error occurs:


ORA-07445: exception encountered: core dump [ksxpcnhent()+155] [SIGSEGV] [Address not mapped to object] [0x409722A68C] [] []

The call stack will resemble the following:


ksxpcnhent <- ksxpvsnd <- kjcts_sndmsg <- kjctcsnd <- kjctcisnd <- kjccsmg <- kjssoc2d <- kjrmas1 <- kjuocl <- kjusuc <- ksipgetctx <- kqlmli <- kgllkal <- kglget <- kglgob <- kgldpo0 <- ...

It is possible to see other errors to due to this memory corruption, most likely dumps in kghalf() or kghprmalo().
