最近我的服务器开始消耗更多的内存。运行进程变为 500+。在过去的一年里，这从未发生在我身上。我有 VPS / 2GB / Ubuntu / Virtualmin。
Apache 有MaxClients 256默认值ServerLimit(256)。最大用户进程数 ( ulimit -u) 为 15891。
错误日志文件/var/log/virtualmin：
mod_fcgid: can't apply process slot for /home/seekdl/fcgi-bin/php5.fcgi
/var/log/apache2：
server reached MaxClients setting, consider raising the MaxClients setting
