yes same problem here 8 identical machines but two seg fault just about every day on login to imp Previous Comments: ------------------------------------------------------------------------ [2003-07-19 22:15:50] gonzalo at linuxaus dot com Hi, I know it's been almost a year since closing bug #19482 but I'm having a very similar issue, only that it's difficult to reproduce. Sometimes, mainly when someone is using IMP, child processes tend to segfault quite a bit. As I said, I can't reproduce it easily so it's hard to know whether whatever I try fixes it or not.. it's just a matter of time :) I'm running Apache 1.3.27, PHP 4.3.1, Horde 2.2.3, IMP 3.2.1 Have you had any similar reports recently? ------------------------------------------------------------------------ [2002-10-07 12:25:02] [EMAIL PROTECTED] This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ [2002-10-07 11:44:06] amith at xalan dot com I applied the patch to php4-200209191800 (the newest snapshot died with some other unrelated problem) and ran my normal tests. Looked like this fixed it! I went through 174 emails with IE and had no segfaults. Thanks for everyone's help in solving this problem and continue with the good work. ------------------------------------------------------------------------ [2002-10-07 11:16:59] [EMAIL PROTECTED] Please try this patch and report back: RCS file: /repository/php4/ext/pcre/php_pcre.c,v retrieving revision 1.128 diff -u -2 -b -w -B -r1.128 php_pcre.c --- ext/pcre/php_pcre.c 11 Sep 2002 14:41:25 -0000 1.128 +++ ext/pcre/php_pcre.c 7 Oct 2002 16:05:59 -0000 @@ -67,4 +67,5 @@ #if HAVE_SETLOCALE if ((void*)pce->tables) pefree((void*)pce->tables, 1); + pefree(pce->locale, 1); #endif } @@ -303,5 +304,5 @@ new_entry.preg_options = poptions; #if HAVE_SETLOCALE - new_entry.locale = locale; + new_entry.locale = pestrdup(locale, 1); new_entry.tables = tables; #endif ------------------------------------------------------------------------ [2002-10-06 22:41:36] amith at xalan dot com I tried with the newest snapshot but I get the following backtrace (gdb) run -X -DSSL -f /usr/local/apache/conf/httpd.conf Starting program: /usr/local/apache/bin/httpd -X -DSSL -f /usr/local/apache/conf/httpd.conf Program received signal SIGSEGV, Segmentation fault. 0x403d2e94 in _efree (ptr=0x0) at /usr/local/software/php4-200210061800/Zend/zend_alloc.c:211 211 CALCULATE_REAL_SIZE_AND_CACHE_INDEX(p->size); (gdb) bt #0 0x403d2e94 in _efree (ptr=0x0) at /usr/local/software/php4-200210061800/Zend/zend_alloc.c:211 #1 0x403e5b8e in zend_hash_destroy (ht=0x82ea824) at /usr/local/software/php4-200210061800/Zend/zend_hash.c:550 #2 0x403e063a in _zval_dtor (zvalue=0x81802ec) at /usr/local/software/php4-200210061800/Zend/zend_variables.c:51 #3 0x403f1206 in execute (op_array=0x82d130c) at /usr/local/software/php4-200210061800/Zend/zend_execute.c:449 #4 0x403f411a in execute (op_array=0x82182e4) at /usr/local/software/php4-200210061800/Zend/zend_execute.c:1641 #5 0x403e1adc in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /usr/local/software/php4-200210061800/Zend/zend.c:834 #6 0x403bbfed in php_execute_script (primary_file=0xbffff6d0) at /usr/local/software/php4-200210061800/main/main.c:1542 #7 0x403fb4b6 in apache_php_module_main (r=0x816c9e0, display_source_mode=0) at /usr/local/software/php4-200210061800/sapi/apache/sapi_apache.c:55 #8 0x403fbfd6 in send_php (r=0x816c9e0, display_source_mode=0, filename=0x0) at /usr/local/software/php4-200210061800/sapi/apache/mod_php4.c:564 #9 0x403fc02a in send_parsed_php (r=0x816c9e0) at /usr/local/software/php4-200210061800/sapi/apache/mod_php4.c:579 #10 0x0806bdcf in ap_invoke_handler () #11 0x08080e53 in process_request_internal () #12 0x08080eb4 in ap_process_request () ---Type <return> to continue, or q <return> to quit--- #13 0x08077df1 in child_main () #14 0x08077fc0 in make_child () #15 0x08078134 in startup_children () #16 0x080787ac in standalone_main () #17 0x0807902b in main () #18 0x42017499 in __libc_start_main () from /lib/i686/libc.so.6 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
