Sidekiq crash on startup

Hi,
It try to set up GitLab frrom source but Sidekiq crashes at start. Here is the trace in sidekiq log :

2015-04-12T20:48:39.857Z 8845 TID-orc2u7iak WARN: Sidekiq died due to the following error, cannot recover, process exiting
2015-04-12T20:48:39.857Z 8845 TID-orc2u7iak WARN: can't create Thread: Resource temporarily unavailable

From my search, it seems that it comes from ressources but :

• I’ve set one worker
• My server is 2Gb and 1.5Gb free.

I’m using mysql … I don’t know if it is start point …

Here is the info of environnement :

Thanks for you help.

I’m still facing the issue … I’ve a new setup (Third time) but with postgresql and I’ve the same message in Sidekiq trace log …

Thanks again for any help !

After another try, I decided to re-test with the deb package … but again : trouble.

In the middle of the reconfigure : everything failed as two processes uses more than 50% of CPU (seems to be sidekig and unicorn …)

Usually running reconfigure a second time fixes any issues. Did you try that? Also it would be great if you provided any logs or error messages.

At the moment, I’ve nothing running as I uninstall everything …

About log …
For the source install : Ive nothing more that the message in the first page …

For the deb package : the error is “no ressource available” or somthing else … As I wrote, two processes take every CPU …

If you have something that I need to follow.

Thanks
