I have a number of applications made in a business basic 4GL generator that run in linux emulation (the Run Time manufacturer has no Fbsd port - and due to the answers to my questions I think they will never port it-). All is working fine but.. there is a called "Ghost Tasks" that use share memory and semaphores... this utilities hang when I try to "invoke" them. Doing some tracing I've found a pair of clues: The first time the application is invoked in a "just-booted" system it shows a: "LINUX: ipc typ 17 not implemented".. it comes from the /sys/compat/linux/linux_ipc.c source. Making a ktrace and comparing it with a strace in a linux system (where this doesn't fail) in the same conditions it shows that it hangs in the place where it would have to do a semop and following it a fork (to detach the so called "ghost task").. Has anithing of this sense to anybody?.. any clue? Thanks a lot for any idea I can follow to resolve this question To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-emulation" in the body of the message
