Thank you John, Is it possible to get more info about this error? For example what file cannot be mapped? It is very hard to find out what can I do to fix the problem. Best regards, Denis > Where can I get description about error with number 22? The error codes are in /usr/include/sys/errno.h header. #define EINVAL 22 /* Invalid argument */ The extended description for the problem you ran into is "can't map file".
