So now chef server still relies on erlang?

The thinking was that this depsolver, while less robust, would be faster and allow for easier installs of the server, since it didn't rely on gecode. It was thought that the edge cases that gecode handled that the Erlang depsolver didn't would only affect a few people. That was a bad assumption. It turns out that many cookbooks have dependencies that are hard to solve for and the Erlang depsolver wasn't up to the task, where as gecode was. With the 11.1 release the server switched back to using gecode. Noah is right that upgrade to at least 11.1 should help you out. If you don't want to jump straight to 12, which is a more involved upgrade process, you can upgrade to 11.1+ by installing the package and then using the chef-server-ctl upgrade.

> I've noticed that my chef server, which is running version 11.0.12-1, slows down over time. It takes about a week to become totally unresponsive. A reboot fixes the issue every time. Affects cookbook uploading and client communication. Hasn't just happened once, but repeatedly.

"Paramapurusha é meu pai e Parama Prakriti é minha mãe. O universo é meu lar e todos nós somos cidadãos deste cosmo. Este universo é a imaginação da Mente Macrocósmica, e todas as entidades estão sendo criadas, preservadas e destruídas nas fases de extroversão e introversão do fluxo imaginativo cósmico. No âmbito pessoal, quando uma pessoa imagina algo em sua mente, naquele momento, essa pessoa é a única proprietária daquilo que ela imagina, e ninguém mais. Quando um ser humano criado mentalmente caminha por um milharal também imaginado, a pessoa imaginada não é a propriedade desse milharal, pois ele pertence ao indivíduo que o está imaginando. Este universo foi criado na imaginação de Brahma, a Entidade Suprema, por isso a propriedade deste universo é de Brahma, e não dos microcosmos que também foram criados pela imaginação de Brahma. Nenhuma propriedade deste mundo, mutável ou imutável, pertence a um indivíduo em particular; tudo é o patrimônio comum de todos."
