我有一些php-fpm的过程总是在增长。

显示使用的内存(使用ps命令)显示了这一点。

我尝试了两件事:

1)strace,但有大量的信息。这是一个Symfony框架,我看到大量文件被访问或打开,但根本没有任何线索。无休止的日志...每1或2或3秒,它突然显示2000行痕迹。

我看到了这个:

fstat(7, {st_mode=S_IFREG|0644, st_size=1029, ...}) = 0
fstat(7, {st_mode=S_IFREG|0644, st_size=1029, ...}) = 0
fstat(7, {st_mode=S_IFREG|0644, st_size=1029, ...}) = 0
mmap(NULL, 1029, PROT_READ, MAP_SHARED, 7, 0) = 0x7f88da53d000
munmap(0x7f88da53d000, 1029)            = 0
close(7)                                = 0
chdir("/")                              = 0
clock_gettime(CLOCK_MONOTONIC, {21720, 148391054}) = 0
times({tms_utime=6933, tms_stime=7614, tms_cutime=0, tms_cstime=0}) = 1720128933
close(11)                               = 0
setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
umask(022)                              = 0
sendto(12, "\1\0\0\0\1", 5, MSG_DONTWAIT, NULL, 0) = 5
close(12)                               = 0
fcntl(6, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0
munmap(0x7f88ba000000, 2097152)         = 0
setitimer(ITIMER_PROF, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
clock_gettime(CLOCK_MONOTONIC, {21720, 149294252}) = 0
accept(0, 

然后它停止1-5秒,它显示了2000行的框架的许多lstat文件...像这样的块的houndreds(这是一个例子,但所有块是不同的

lstat("/var/www/vhosts/mywebsite.com/vendor/composer/../symfony/swiftmailer-bundle/DependencyInjection/SmtpTransportConfigurator.php", {st_mode=S_IFREG|0644, st_size=1029, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com/vendor/composer/../symfony/swiftmailer-bundle/DependencyInjection", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com/vendor/composer/../symfony/swiftmailer-bundle", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com/vendor/composer/../symfony", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com/vendor/composer", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com/vendor", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com", {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0
lstat("/var/www/vhosts/mywebsite.com", {st_mode=S_IFDIR|0710, st_size=4096, ...}) = 0
lstat("/var/www/vhosts", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/www", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0

2)lsof但我无法获得有关脚本的信息或原因。

你的内存使用的主要问题是你必须附加调试器或分析器来诊断,并且很可能是应用程序本身内存泄漏而不是PHP固有的任何内容。作为权宜之计,你可以配置FPM以更频繁地回收其工作人员以释放累积的内存。

你遇到的第二个问题是你的作曲家自动加载器仍然在每次加载时遍历文件系统,这似乎是你有如此大量lstat调用的原因。这对你的内存使用没有影响,但是很多不必要的IO可以很简单地避免:
