I have installed the recent version of galaxy and starting multiple web and job handlers(six each) on a Centos 5.1 machine. 

It is working almost perfectly. 

1. The first problem is sometimes jobs never start and they are in grey stage. After I killed them and start again, they work fine. There are no any log about why they haven’t started. So, if you direct me to find the reason, it would be great. 

2. Second problem is about UCSC visualization issue using the links from history. I haven’t found a solution yet, my XSendFile is all set and working in the previous version but not this one. 

The only difference is I am using the new version and balancer in Apache since I run multiple instances. So, balancer might not use XSendFile properly or there is a configuration problem.   

Let me know, if anybody has a similar settings and solved this problem with Apache.

Best,
