[hobbit] Problems starting hobbit

[Kasperowicz, Shaun]

Thanks Henrik,  I was able to delete the stale shared memory segments
and start hobbit.  Still getting some errors in hobbitlaunch.log though:

2006-06-21 10:10:21 hobbitlaunch starting

I assume these are not normal?  Hobbitd is running, but no web pages are
being generated.

Thanks,

-Shaun

The "Permission denied" error is odd, it indicates that this shared
memory segment already exists, but was created by another user.

If you login as root and run "ipcs -m" you'll get a list of the
existing shared memory segments. With hobbit running, it typically
looks like this:

------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status
0x0102b575 2031619    hobbit    600        262144     2
0x0202b575 2064388    hobbit    600        262144     2
0x0302b575 2097157    hobbit    600        262144     2
0x0402b575 2129926    hobbit    600        262144     2
0x0502b575 2162695    hobbit    600        262144     1
0x0602b575 2195464    hobbit    600        32768      1
0x0702b575 2228233    hobbit    600        524288     2
0x0802b575 2261002    hobbit    600        524288     2

The "bytes" and "nattch" are typical for a default Hobbit setup.

If a Hobbit run has crashed, it might leave these behind. In that case,
use "ipcrm" to delete them. (Hobbit will do that automatically when
restarting, but if they were created by another user then it cannot).

Henrik
