Apache2 Debian服务器下降。 内存不足

帮助我，请与我的Apache的问题。 我在DigitalOcean上得到了512MB的内存（Debian）。 MODX CMS上有3个站点（在PHP上运行）。 今天早上，因为我认为系统发现了一个内存不足的问题，并开始杀死进程（有约43 apache程序）。 它杀死了mysqld，并开始逐个杀死apache2。 你能指点我哪个configuration我必须调整？ 对于mysql的Tuning-primer.sh来说，内存分配没有问题。

这是我的my.cnf：

key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 myisam-recover = BACKUP max_connections = 70 max_heap_table_size = 25M tmp_table_size = 25M query_cache_limit = 1M query_cache_size = 25M [mysqldump] quick quote-names max_allowed_packet = 16M [isamchk] key_buffer = 16M
