我正在尝试在Intel Xeon E5-2620v4的Debian 8.5上安装扭矩6.0.2。但是，当我尝试启动pbs_server时，使用gdb返回了段错误：

没有其他软件具有此行为，我在满负荷的情况下经过2天的测试，没有出现问题。已经尝试更新处理器微代码。请问有人在扭矩6.0.2或其他情况下有这种行为吗？
最好的祝福。
最佳答案
这不是微码错误。无论您运行的是什么软件（而不是glibc / libpthreads），这都是一个完全的锁平衡问题。
不要尝试解锁已经解锁的锁。这是被禁止的行为，也是造成陷阱的原因。
出于性能方面的考虑，glibc无需费心测试它和段错误，因此很长一段时间以来，很多损坏的代码都没有得到使用。锁定省略（OTOH）的硬件实现确实会引起陷阱（Intel TSX，IBM Power 8，S390 / X ...），因此这种破损将很快出现在任何地方。
