The following tests fail in the RT baseline nightly on Linux amd64 and i586 in mixed mode:
  bigapps/Weblogic+medrec/startup
  bigapps/Weblogic+medrec/startup_posprocess_analyzer

with the assert:

# Internal Error (/opt/jprt/T/P1/223506.ddaugher/s/src/share/vm/services/memSnapshot.cpp:622), pid=21805, tid=140612911077712
# assert(new_rec->is_allocation_record()) failed: Sanity check


This is a fragment from the hs_err dump:
