Hello, Our test server crashed this night and yesterday night, at the same time, but I can't find a reason ... Can anyone help ??? The errno 36 is : /usr/include/sys/errno.h #define EIDRM 36 /* Identifier removed */ but I don't really understand.

Looks like you may have a sweeper in a cron that removes shared memory segments or semaphores! Have your ALARMPROGRAM script run: ipcs -a and output to a file and compare the report in one you took the evening before. If any of the informix owned segments are missing bingo now you just have to find the cron job which would have to be owned by informix or root to do damage. Sounds like an aggressive SysAdmin trying to cleanup the day's messes overnight. Art S.
