You can safely go to buffer size 100 Mbytes or more.

Good.

This is strange. How old is your midas? What does it say on the "help" page in "Revision"?

This command is wrong. It probably gave you an error instead of removing the shared memory, that's why
nothing worked afterwards.

My copy of system.c reads this:
cm_msg(MERROR, "ss_shm_open", "Shared memory segment with key 0x%x already exists, please remove it manually: ipcrm -M 0x%x", key, 
key);

Note how there is no text "size0x..." in my copy? What does your copy say? Did somebody change it?

Yes, that's because the ipcrm command is wrong and did not work,
it should read "ipcrm -M 0x4d040761" without the spurious "size..." text.

K.O.
