I am sorry for my late reply memory in my PC is 16 GB I check the contents of .SHM_TYPE.TXT and it is "POSIXv2_SHM". But there is no buffer
sizes in "/Experiment" After run "ipcrm -M 0x4d040761 size0x204a3c", remove .SYSTEM.SHM and run MIDAS again, I still get error "Shared
memory segment with key 0x4d040761 already exists, please remove it manually: ipcrm -M 0x4d040761 size0x204a3c" M.T |

12 Dec 2011, Michael Murray, Bug Report, bk_delete uses memcpy instead of memmove
