我有一些php-fpm的过程一直在增长。
显示使用的内存（使用ps命令）显示此内容。
我尝试了两件事：
1）strace，但是有大量的信息。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。我明白这一点：
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，但所有块不同
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", {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。
