Here's a HOW-TO for the deadlock on start-up problem that Xron has on some systems. -- Loren

Hi Loren,
IT WORKS !!! :)
We have tested also Xron DTML method calling an SQL method and it seems to work.

Here's an idea that just occurred to me today. You may want to try it out. It might work, but I can't try it out, as I can't reproduct the problem you have encountered. It will only work if Xron appears on the Control Panel as an already installed (though perhaps broken) product.
1. Install the Refresh product. http://www.zope.org/Members/hathawsh/Refresh
2. Rename the __init__ file of Xron to something else, so that Xron won't be loaded as Zope starts up.
3. Restart zope. Refresh will be loaded, but Xron will not.
4. Rename the __init__ file back to its proper name.
5. Click on the Refresh button on Xron's product page.
Xron should start this time without deadlocking, because the deadlock is due to some interaction with the rest of Zope's startup code.
If this works, let me know.

No, I can't tell you which order to kill the threads, partly because I've never experienced the problem myself -- just heard about it from others -- and partly because, as far as I know, there is no way to distinguish the threads. Also, I don't have a Linux installation here to try it on. So you'll just have to try all combinations. I hope one works for you.

Hello Loren,
I have problems with starting Xron. I get exactly the same problem as described below - Zope freezes after Xron product instalation. Firstly I guessed it was caused cause of old version ( Client.py patch) but now I'm running a completely new instalation of Zope 2.3 on a new computer and still get the same problem. (used Xron version 0.0.9). OS is redhat 6.2.
If you can send me a guide how to determine in which order to kill zope threads or a link to some resources wich resolve this problem I would be very glad.
Thank you in advance.
Eduard Gajdos.

There is a problem on some systems that causes a newly installed Xron to deadlock during the product initialization process. Using ps you can see the Zope threads. You will have to kill each thread. If you kill them in the right order, Xron will initialize properly and, after you restart Zope, you won't have any further problems. I can't tell you how to determine what the right order is. Good luck.
