Hi, Richard
I enabled Olio/PHP on SWS7u6 on Linux, however I met the below error
when running Olio only with 100 users.
[19/Oct/2009:15:35:25] catastrophe (22588): CORE3260: Server
crash detected (signal SIGSEGV)
[19/Oct/2009:15:35:25] info (22588): CORE3261: Crash occurred
in NSAPI SAF php5_execute
I wonder which php module is not thread-safe? I only enabled apc and
memcache in php.
php was compiled as
CC="gcc" CFLAGS="-O3 -fPIC" ./configure
--prefix=/home/sun/php-5.2.6 --with-mysql=/usr/local/mysql
--with-gettext --with-zlib --with-nsapi=/home/sun/webserver7/
--enable-force-cgi-redirect --with-pdo-mysql=/user/local/mysql
--with-curl --with-gd=/home/apache_webserver/gd-2.0.35
--with-jpeg-dir=/home/apache_webserver/jpeg-6b
apc3.0.19 was compiled as
CC="gcc" CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3" ./configure
--enable-apc --enable-apc-mmap
--with-php-config=/home/sun/php-5.2.6/bin/php-config
memcache-2.2.5 was compiled as
./configure --enable-memcache
--with-php-config=/home/sun/php-5.2.6/bin/php-config
Your suggestions/comments are appreciated.
Thx, Xuekun
