I'm using 7.1.5 and SQLSE on a shared server. Everything has been working great until today. The site is just blank.
I can get in to the back end and it greeted me with this message
Server error: Contact administrator, see log for full details.
Failed to retrieve data for content id xxxx
In the log i got a couple of error messages saying:

I have no clue whats going on. I can't ping the site. Tried republish it, restart the server, triple checked folder permissions.
How about removing the TEMP folder AS well (you might have to stop IIS if there is lock file). Then restart/republish the site hopefully then Luceene/Examine will rebuild the site.
For future reference. The error kept happening and it seems to be the same issue as this http://issues.umbraco.org/issue/U4-6626. I upgraded to 7.2.6 and it hasn't occurred since fingers crossed.
I've just been hit by this issue in 7.2.8 after restarting the website. Getting several Failed to enter the lock within timeout exceptions in the server's event viewer.
Just been hit with this, but not for the first time - but as my system had been running smoothly for a couple of days, investigated this issue.
It's IIS express. My set up is VS2015 (built in IIS Express) and Umbraco 7.3.0.
VS2015 (and VS2013 as I understand) has it's own config files for IIS, it does not use the IIS config. To this end, as I built one project, another was starting at the same time. It appears that if you have 2 projects open at the same time and debug one, it overwrites the VS config.
Having added each project to IIS config, both started without issue.
Will add that this has been an intermittent issue, only today did I follow it further. If it happens with you again, this may be worth looking at.
Have seen a fix to change setting in template, but have no proof that it is working.
Hi Gary,
I am still stuck with that issues , my site is going down after 1 or two days for 7-10 minutes of downtime . i have gone through your comment but the solution is still not clear to me :( (sorry for that) . can you please point me to right direction to resolve this issue?
The issue was definitely a server issue. (IIS in my case).
If I remember correctly I had to manually register the site as two sites had the same id, therefore it was firing two http requests. One would time out, lock, the other run, as I switched the front end page, the other would run and the first time out lock.
If your host can provide info on the fail, this may be a similar case. If so it could be something in the config, like default session provider , version or similar.
I also had this error after upgrading to Umbraco 7.5.12. Now upgraded to 7.5.13 and it's fixed again. Was related to this issue: http://issues.umbraco.org/issue/U4-9752

Have you tried deleting the /App_Data/umbraco.config file then restarting your site?
(recommend backing up the file first to get back to square one if this doesn't work).
Good luck if this isn't the answer.
No i hadn't. I tried and it didn't regenerate a new one.

OMG I LOVE YOU JOHN! It worked!!!
I can only mark my own answers as solutions. I guess it's a bug in the new our. I'll mark it as solved as soon as it's possible. <3333

Sadly, no, but I also haven't seen the issue recently.

Is there any news? I'm too worry about it, because i read a lot of posts about this problem and there is no solution.... My Umbraco version is 7.5.6
I also had this error after upgrading to Umbraco 7.5.12. Now upgraded to 7.5.13 and it's fixed again. Was related to this issue: http://issues.umbraco.org/issue/U4-9752
