failed to enter the lock within timeout

I am facing a very strange error "failed to enter the lock within timeout" . because of this error my website fails silently. i am using umbraco version 7.2.5. it is running over IIS v8. Please note i have not changed any config settings or any other thing and strangely my website goes down, and now i am not able to recover from this. any help will be highly appreciated.

Hi Shobhit

This is a known issue in that specific version of Umbraco - According to this issue http://issues.umbraco.org/issue/U4-6626 it should be fixed in version 7.2.6 so an upgrade should be fixing it.

If you need a quick fix you should be follow the advice from the post marked as the solution in this post https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/66447-web-site-fails-silently - However you'll need to upgrade to avoid this from happening again permanently.

You can read more about upgrading here https://our.umbraco.org/documentation/Getting-Started/Setup/Upgrading/ - Make sure to make a backup of everything before doing so (Files and DB) so you're not lost if something does not turn out right in the process.

Hope this helps.

/Jan

Anyone still having this issue? I am running v7.4.1 and I am still getting this error approximately every 30mins on a live site.

Follwing actions has been taken to resolve this:

Enabled 32 bit on IIS: reduce memory usage, when using the default (64bit) memory usage was so high, btw 2 to 3.5 gig
Removed backend examine
Disabled overlap recycle to true: This ensures the old worker process is removed before creating a new one.

I am running out of ideas now, considering that I am running v7.4.1 that this issue may have been fixed.

Any help/suggestion will be much appreciated.

Experiencing this on 7.5.4 as well. Site goes YSOD approx once per week. No ideas on how to fix. Have you had luck with your steps above (32 bit and disable overlap?)
