Status: RESOLVED DUPLICATE of bug 481549

(Bugzilla :: Administration, task)

Description

[geoff.taylor]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b5) Gecko/2008042803 Red Hat/3.0b5-0.beta5.6.el5 Firefox/3.0b5
Build Identifier: version 3.6.1

I am testing an upgrade of Bugzilla from version 3.0 to version 3.6.1.

After successfully running checksetup.pl, I was exploring the Administration UI,
I am unable to use editproducts.cgi for only one of our products.
The rest of the products are OK.

For the one product, seeing this error:

Bugzilla has suffered an internal error. Please save this page and send it to with details of what you were doing at the time this message appeared.

URL: http://agate.qlogic.org/bugzillasb-3.6.1/editproducts.cgi?action=edit&product=FC%20Switch%20Firmware
undef error - Not an ARRAY reference at Bugzilla/Object.pm line 267. 

The product in question had close to 1000 versions. After removing versions until the total dropped to ~470, the error disappeared. Adding versions to make the total greater than 502 results in the error returning.

I am seeing the same problem when trying to run show_bug.cgi for any bugs for the same product:

Reproducible: Always

Steps to Reproduce:
1. Add versions for a single product until the total is above ~502.
2. Try to display editproducts.cgi for the same product.
3. Or try to display any bug for the same product.
Actual Results:

Expected Results:  
Page displays requested info.

This problem does not occur with our current Bugzilla version 3.0 installation. We are running with MySQL 4.1 on RHEL4.
My sandbox is running MySQL 5.1 on RHEL5.
FWIW, the browser I am running is Firefox 3.
