Package: libapache2-mod-php5
Version: 5.1.6-5
Severity: important
Hello,
I run a webserver with some PHP sites and I'm stuck with PHP version 5.1.6.
I'm unable to upgrade to version 5.2.0 because suddendly apache processes begin
to loop using 100% cpu time and after the while the whole system becomes
unresponsive and I need to shutdown apache2 to gain control.
I tried to attach to a process with strace and this is what I get:
[...]
lstat("/var", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/home", {st_mode=S_IFDIR|0755, st_size=85, ...}) = 0
lstat("/var/home/web2", {st_mode=S_IFDIR|S_ISUID|S_ISGID|0775, st_size=52, ...}) = 0
lstat("/var/home/web2/lc", {st_mode=S_IFDIR|S_ISGID|0775, st_size=95, ...}) = 0
lstat("/var/home/web2/lc/www", {st_mode=S_IFDIR|0750, st_size=4096, ...}) = 0
lstat("/var/home/web2/lc/www/site", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/var/home", {st_mode=S_IFDIR|0755, st_size=85, ...}) = 0
lstat("/var/home/web2", {st_mode=S_IFDIR|S_ISUID|S_ISGID|0775, st_size=52, ...}) = 0
lstat("/var/home/web2/lc", {st_mode=S_IFDIR|S_ISGID|0775, st_size=95, ...}) = 0
lstat("/var/home/web2/lc/www", {st_mode=S_IFDIR|0750, st_size=4096, ...}) = 0
lstat("/var/home/web2/lc/www/site", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
[...]
over and over and over.
The web site on that directory is a standard XOOPS site, and it worked fine for all
the others PHP versions since Sarge released.
Any hints?
