Signal 11 when indexing

Hi.
I created scripts to index my site nightly and for some time all worked fine. But then I discovered that some pages are not indexed any more. Then I tried manually and found out that there was error when indexing new pages:

[andres@... search]$ /u2/search/bin/gw -d/u2/search/data/db -r -index
Indexing new pages
000 Got signal 11 - quitting now

What can be reason of that?

A corrupt index or db is usually the cause, and usually because the machine either ran out of disk space or crashed amid an index update.

Try:

gw -unindex
gw - index

and see if this resolves the matter.

Nope. Exactly same error.

I tried to remove all files from .../db/ directory to create totally new db but this doesn't succeeded as well.. Then I got messages like:

Database /u2/search/data/db exists, but can not be opened

Ooops...
You shouldn't remove files from the DB directory manually, just the gw -wipe or -unindex commands. At this point you should start over. Remove the directory and then use "gw -d/u2/search/data/db -create"

I didn't removed put moved

But anyway. I just 1 minute ago found out this "-create" parameter and tried this but:

$ /u2/search/bin/gw -d/u2/search/data/db -create
200 Database created
000 Got signal 11 - quitting now

Hmh. After that I tried to index my site and seems that this started to work.... Let see will this end with success....

rm -r /u2/search/data/db
then try -create with -v9 to get a better idea of where it's failing.

What's your OS type and version (uname -a)?
What's your gw version and release (gw -version)?

It looks like you may have downloaded the wrong version (or upgraded your kernel). You should download the version for Linux 2.x, not 1.x.

Yes. This was true. I found out that our sysadmin was updated kernel resently. So I took another version of gw. But... Still errors

We know Webinator works with Linux 2.4.2 and glibc 2.1.3. It should also work with 2.4.3. You need to have System V IPC enabled in the kernel. The ipcs command will give the status of shared mem. Also the /proc/sysvipc should be indicative of whether it's enabled or not.

If you have System V IPC enabled but still have a problem, run gw with strace and send us the output.
strace /u2/search/bin/gw -v9 -d/u2/search/data/db -create
Please also indicate your libc version.
