You don't have to touch the production PHP and Apache - you can always install it into different location and listening on another port. ------------------------------------------------------------------------ [2006-04-25 12:38:28] ivoras at gmail dot com Do you have a reason to believe this will help me - are there any changes in the session serializing code between the two versions? (This is a production machine and I can't risk downtime when I try the snapshot). ------------------------------------------------------------------------ [2006-04-25 12:09:11] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-04-25 12:07:36] ivoras at gmail dot com Description: ------------ PHP module in apache randomly crashes. Tried building debug version of PHP, but it doesn't change anything (there is no significant additional data in apache error logs). Attached is the result of Apache modules mod_whatkilledus and mod_backtrace. The problem seems to be this: "httpd in malloc(): error: recursive call" Talking to FreeBSD developers, this most likely happens if an application tries to use malloc() from a signal handler, while another malloc() is in progress, which apparently is allowed by GNU malloc() but not by BSD malloc(). Reproduce code: --------------- Cannot pinpoint crash location - possibly random or before/after PHP code starts to execute. Expected result: ---------------- Normal operation. Actual result: -------------- [Tue Apr 25 13:46:26 2006] pid 28734 mod_whatkilledus sig 6 crash [Tue Apr 25 13:46:26 2006] pid 28734 mod_whatkilledus active connection: 194.213.26.11:60632->161.53.72.111:80 (conn_rec 8498128) [Tue Apr 25 13:46:26 2006] pid 28734 mod_whatkilledus active request (request_rec 849e050): GET /zvne/alumni?_v1=U-7HlKuFSMHIHduAAExHdmGM_tcn2Vp3MqonoAYek-3EDnfH4VQDVQjKNRBSm6hh&_lid=10213 HTTP/1.1|User-Agent:Mozilla/5.0 (compatib le; Pogodak.hr/3.1)|Cookie:phpbb2mysql_sid=c61f99db46b5a2b837340e294ccb5a5a; phpbb2mysql_data=a%253A2%253A%257Bs%253A11%253A%2522autologin id%2522%253Bs%253A0%253A%2522%2522%253Bs%253A6%253A%2522userid%2522%253Bi%253A-1%253B%257D; CMS=6c9d1e5a98c7927a10ff0d0d47e902e1; CMS=6c9d 1e5a98c7927a10ff0d0d47e902e1|Accept-Language:hr|Cache-Control:no-cache|Pragma:no-cache|Host:www.zvne.fer.hr|Accept:text/html, image/gif, i mage/jpeg, *; q=.2, */*; q=.2|Connection:keep-alive|Content-type:application/x-www-form-urlencoded [Tue Apr 25 13:46:26 2006] pid 28734 mod_whatkilledus end of report [Tue Apr 25 13:46:26 2006] pid 28734 mod_backtrace backtrace for sig 6 (thread "pid" 28734) [Tue Apr 25 13:46:26 2006] pid 28734 mod_backtrace main() is at 806a950 0x8071e65 <ap_run_fatal_exception+53> at /usr/local/sbin/httpd [EMAIL PROTECTED] <ap_run_fatal_exception+255> at /usr/local/sbin/httpd [EMAIL PROTECTED] 0x284133d4 <abort+84> at /lib/libc.so.6 0x283b9b03 <_UTF8_init+1875> at /lib/libc.so.6 0x283b9b31 <_UTF8_init+1921> at /lib/libc.so.6 0x283babb8 <_UTF8_init+6152> at /lib/libc.so.6 0x28653915 <_emalloc+197> at /usr/local/libexec/apache2/libphp5.so 0x28632152 <vspprintf+382> at /usr/local/libexec/apache2/libphp5.so 0x2862e68b <php_set_error_handling+159> at /usr/local/libexec/apache2/libphp5.so 0x28669809 <zend_error+165> at /usr/local/libexec/apache2/libphp5.so 0x2865f60d <zend_timeout+53> at /usr/local/libexec/apache2/libphp5.so 0xbfbfff94 0x28653cb7 <_erealloc+179> at /usr/local/libexec/apache2/libphp5.so 0x28611c63 <zif_var_export+4139> at /usr/local/libexec/apache2/libphp5.so 0x28611abd <zif_var_export+3717> at /usr/local/libexec/apache2/libphp5.so 0x28611abd <zif_var_export+3717> at /usr/local/libexec/apache2/libphp5.so 0x28614a87 <php_var_serialize+23> at /usr/local/libexec/apache2/libphp5.so 0x2894ec16 <ps_srlzr_encode_php+290> at /usr/local/lib/php/20050922-debug/session.so 0x2894f117 <ps_srlzr_decode_php+507> at /usr/local/lib/php/20050922-debug/session.so [Tue Apr 25 13:46:26 2006] pid 28734 mod_backtrace end of backtrace [Tue Apr 25 13:46:27 2006] [notice] child pid 28734 exit signal Abort trap (6) httpd in malloc(): error: recursive call ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37197&edit=1
