Question

Recentemente, descobri que alguns aplicativos do Mac OS X estão travando frequentemente com backtraces como os seguintes:

Alguma idéia sobre o que pode estar causando isso e / ou como remediá-lo?

    

Answer 1

Eu não sou um programador de kernel, mas acredito que a mensagem tenha algo a ver com a falta de portas Mach no kernel. Você tem um zilhão de processos em execução ou está fazendo muita comunicação entre processos? Você está possivelmente com pouca memória e espaço em disco (não há espaço para expandir sua troca)?

Tente usar top ou Activity Monitor para ver se você tem algum processo enlouquecendo, como talvez você tenha escrito um AppleScript recursivo ou um shell script que gera zilhões de processos filhos (como uma "fork fork" acidental). / p>

Preste atenção em quais aplicativos você está executando ao atingir esse problema. Talvez haja um aplicativo que use portas Mach e, às vezes, engula todas elas. É mais provável que este problema aconteça quando você está executando um sistema de máquina virtual como VMware, Parallels ou VirtualBox?

Hmm. Tentei redefinir o SyncServices --- link --- e o Mail não travou desde então.
