无效参数：AH03139：ap_queue_pop 失败

无效参数：AH03139：ap_queue_pop 失败

简而言之，我从 Fedora Server 23 升级到了 Fedora Server 24，现在我的 apache（httpd-2.4.23-4.fc24.x86_64）error_log 充满了这些消息：

[Mon Nov 28 20:30:39.486187 2016] [mpm_worker:crit] [pid 9973:tid 140499117635328] (22)Invalid argument: AH03139: ap_queue_pop failed
[Mon Nov 28 20:30:39.486197 2016] [mpm_worker:crit] [pid 9973:tid 140499117635328] (22)Invalid argument: AH03139: ap_queue_pop failed

（它触发了磁盘空间警报，当它达到 1.8Gb 时我修剪了 error_log！）

我正在使用 MPM 工作器，其设置如下：

任何意见，将不胜感激。 ：）

编辑：最后，我认为服务器总体上不稳定，所以放弃了它，从头开始构建了一个新服务器。我始终没能解决这个问题。

您的系统限制似乎不够高，导致 Apache 进程出现问题。您可能需要增加max user processes、pending signals和的值open files。以下是一些可取的值：

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 1546671
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 102400
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 1546671
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited
