Robert,
I also experience this problem with Zebra version 2.0.37 and YAZ 3.0.34
On another installation with Zebra 2.0.43 and YAZ 3.0.49 (and less memory!), it does not happen.
Try upgrading Zebra/YAZ?

Regards,
Marcel

Robert,
Not a solution & may not be relevant information, but I had segfaults when trying to run zebra indexing with 80000 plus records on a 1Gb memory machine. Adding memory resolved the issue.

Here is a bit more information about the segfaults that I am experiencing.
By following the tail of syslog, I noticed that they are preceded by an operation waiting to run, then followed by a flood of messages, 4 per second, about operations waiting to run. If I manually run:

KOHA_CONF=/etc/koha/koha-conf.xml PERL5LIB=/usr/share/koha/lib/ /usr/share/koha/bin/migration_tools/rebuild_zebra.pl<http://rebuild_zebra.pl> -b -a -z

The log flooding stops, until the next time.

Here is a snip from the syslog:

Thank you Jared. I made the changes you recommended and then restarted /etc/init.d/koha-zebra-daemon but the problem persists. Any other Ideas?

Robert,

I don't recall if this is the error that we encountered, but you might try increasing the amount of space available for the register and shadow directories. In ${KOHADIR}/etc/zebradb/zebra-biblios.cfg change 4G to 16G (or something like that) in these lines:
register: __ZEBRA_DATA_DIR__/biblios/register:4G
shadow: __ZEBRA_DATA_DIR__/biblios/shadow:4G

If you have koha set up to run out of kohaclone and koha-dev, you need to modify the configuration file in koha-dev. As I said, I can't remember the exact error message we got, but I think it involved a segfault, so you might as well try our fix.

Regards,
Jared Camins-Esakov

Good morning!

I'm a noob to this list, so first, an introduction. I am charged with supporting a Koha installation at a small educational Library, roughly 90,000 items in catalog.

Current problem:
Apr 28 10:44:08 <servername> kernel: [66486.907544] zebrasrv[12570]: segfault at 00000046 eip b64a61e9 esp bfd58518 error 4

Is there an obvious solution, or do I need to provide more information?
