HELP plz: the CMS crash my server on VB 4.2 PL1

[autoescala]

Dear sirs,

Recently, we have lot of problems with or Vbulletin software, every day, we have 3 o 4 big errors "503" with no service, after we update to 4.2 PL1

The ISP says the cause is about a bad or very slow query from "content.php"

The response of ISP: (copy/paste)

"We have analyzed precisely the code 503 refers to us and we see that this code is generated by running:

SCRIPT_FILENAME = content.php

We see that sometimes this script may be running over 20 minutes, causing the server, for security reasons and to avoid saturation of your account, returns the code 503 to generate more requests are not on it that do not end or take a long time.

I think it would be better if you started a ticket at your vb client 's desk about this so the vb staff can investigate this further.

What is your widget 29 (you'll have to look that up in the cms_widget table)? Is it custom? Have you tried removing it from your page to see if you still have the same problem?
