> 2) the shared memory type used by an experiment is recorded in the file .SHM_TYPE.TXT.

An error with creating the file .SHM_TYPE.TXT was corrected in system.c svn rev 5125 - if file did not exist, it is 
created correctly, but MIDAS reports "cannot connect to ODB". Second try works correctly because the file exists 
now.

This is causing problems on mobile computers where "hostname" changes all the time (i.e. set according to 
DHCP on whatever network happens to be connected).

If you run into this problem, keep deleting .SHM_HOST.TXT or use this workaround: disable the hostname check 
by making the file .SHM_HOST.TXT empty (zero length).
