Re: [users@httpd] Segmentation fault
Yep, but at this time this is not a segfault, so without opcache the segfault seems fixed. You are now getting mmap() errno 12 -> ENOMEM -> Cannot allocate memory. This is another type of error that is nothing to do with a segmentation fault. My advice si to disable opcache, check your php.ini configuration (specially memory_limit). Also check your limits (/etc/sysctl.conf and /etc/security/limits.conf). Or, like someone said, switch to PHP-FPM and fastcgi instead (but also check your php.ini and system limits). 11 marzo 2022 19:52, "Ivan Ionut" mailto:ivan.io...@tehnopol-gl.ro?to=%22Ivan%20Ionut%22%20)> wrote: Well, i disabled opcache and after I had other crashes: [crit] Memory allocation failed, aborting process.

Re: [users@httpd] Segmentation fault
Hello, A mod_php segfault is most likely linked to a php extension. You have two options here: 1) Unload each php extension until you find the culprit 2) Switch to php-fpm, and configure httpd to use the event mpm via proxy_fcgi to pass the requests to php-fpm On Wed, 9 Mar 2022 at 08:15, Ivan Ionut wrote: > *My apache2 version:* > > Server version: Apache/2.4.18 (Ubuntu) > Server built: 2020-08-12T21:35:50 > > *My php version:* > > PHP 7.3.7-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Jul 10 2019 > 06:54:26) ( NTS ) > Copyright (c) 1997-2018 The PHP Group > Zend Engine v3.3.7, Copyright (c) 1998-2018 Zend Technologies > with Zend OPcache v7.3.7-1+ubuntu16.04.1+deb.sury.org+1, Copyright (c) > 1999-2018, by Zend Technologies > > *My os version:* > > Distributor ID: Ubuntu > Description: Ubuntu 16.04.6 LTS > Release: 16.04 > Codename: xenial > > > Hi, from last 2-3 months i have a lot of these segmentations(2-3 times > per week); > > [Wed Mar 09 10:47:12.150226 2022] [core:notice] [pid 21823] AH00051: child > pid 22481 exit signal Segmentation fault (11), possible coredump in > /etc/apache2 > [Wed Mar 09 10:47:17.155792 2022] [core:notice] [pid 21823] AH00051: child > pid 21895 exit signal Segmentation fault (11), possible coredump in > /etc/apache2 > [Wed Mar 09 10:47:24.163536 2022] [core:notice] [pid 21823] AH00051: child > pid 22189 exit signal Segmentation fault (11), possible coredump in > /etc/apache2 > [Wed Mar 09 10:47:24.163618 2022] [core:notice] [pid 21823] AH00051: child > pid 22562 exit signal Segmentation fault (11), possible coredump in > /etc/apache2 > [Wed Mar 09 10:47:25.164759 2022] [core:notice] [pid 21823] AH00051: child > pid 22491 exit > > ... > > Every site on the server has an error with: "Secure Connection Failed" or > "The Connection was reset" > > After I restart apache2 everything is ok. > > Before this error..

There's documentation here: http://httpd.apache.org/dev/debugging.html The important first steps are setting CoreDumpDirectory and ulimit -c unlimited. As soon as you have a core dump, grab a .gdbinit from the appropriate apache source (or package), install the debug info for apache and modules (in redhat-like Linux distributions debuginfo-install may help), and check the request record. You may want to print r->the_request and dump_table (r->headers_in) to see some info that may help you reproduce the problem. Segfaults may indicate a security relevant problem.

Thanks William. This is the stack output i got from mdb when core got dumped. Also, when i google "ap_mpm_pod_check" then got to know that there are lots of people who hits Apache bug. Please refer this URL - http://www.gossamer-threads.com/lists/apache/bugs/414768 Also, i ran pfiles against the core file and i got data model = _ILP32 flags = MSACCT|MSFORK /1:flags = 0 sigmask = 0xbeff,0x cursig = SIGSEGV /2: /3:flags = STOPPED lwp_park(0x4,0x0,0x0) why = PR_SUSPENDED sigmask = 0xffbe6007,0xfff7 .. (rest of lines truncted) I don't know much about debugging as i am not from developer background but whatever o/p i got, looks like some bug with Apache 2.2.22. Please revert.

Re: [users@httpd] Segmentation fault error
You didn't dump the offending stack, you dumped the first stack. It's highly unlikely there was a segfault in _read. You need to dump all the thread stacks, and work out the offending one; this is usuallly designated <<< FAULT or some other indication of where the fault occured.

Re: [users@httpd] Segmentation fault error
Thanks Nick. I have compiled Apache for myself both the time and both are 32-bit. The same modules all other instances are using and thus i am not sure what is different with this instance that causing Segmentation fault error. I tried to dig more into it and here is what i got - mdb core > ::stack libc.so.1`_read+0xc(6, ffbff5e3, 1, 0, 10b4, fef73ac0) ap_mpm_pod_check+0x18(d6800, 68764, 68f8c, 1b7ec0, 0, 1) child_main+0x2d4(0, 682dc, 0, fee58000, fef73700, fedf2a00) make_child+0x128(9bc00, 0, 1, 9cc00, 9b400, 9c800) ap_mpm_run+0x740(fe720058, 4, 0, a, 1, 0) main+0x77c(a7810, 99c00, 9bc00, 9bc00, a5808, 0) _start+0x5c(0, 0, 0, 0, 0, 0) pstack core fef45874 _read(6, ffbff5e3, 1, 0, 10b4, fef73ac0) + c 0006b714 ap_mpm_pod_check (d6800, 68764, 68f8c, 1b7ec0, 0, 1) + 18 000697b4 child_main (0, 682dc, 0, fee58000, fef73700, fedf2a00) + 2d4 00069930 make_child (9bc00, 0, 1, 9cc00, 9b400, 9c800) + 128 0006a160 ap_mpm_run (fe720058, 4, 0, a, 1, 0) + 740 00029bc8 main (a7810, 99c00, 9bc00, 9bc00, a5808, 0) + 77c 00028f7c _start (0, 0, 0, 0, 0, 0) + 5c pmap core 0001 448K r-x-- /abc/apache-2.2.22/bin/httpd 0008 32K r-x-- 00096000 24K rwx-- /abc/apache-2.2.22/bin/httpd 0009C000 16K rwx-- /abc/apache-2.2.22/bin/httpd 000A6528K rwx--[ heap ] FAB7A000 8K rw---[ stack tid=36 ] ...

[users@httpd] Segmentation fault error
Hi All, I am using this configurations - Solaris sparc 10/apache 2.2.22/openssl 1.0.0g/simteminder sso/mod-jk 1.30 we are curently running multiple apache servers from the apache's root dir. Only one of the those instances throwing below errors in error_log : [Tue May 19 16:14:06 2012] [notice] child pid 15729 exit signal Bus error (10) [Tue May 19 17:46:24 2012] [notice] child pid 17114 exit signal Segmentation fault (11), possible coredump in /tmp/core we had recently upgraded apache to 2.2.22 version and since then we are seeing above errors. I am not sure what could be the reason. the other instances don't have any problems whereas all instances are using the same modules!

[users@httpd] Segmentation Fault on starting httpd 2.0.48
Hello-
I get a segfault when starting httpd. I'm using apache 2.0.48 built
from tar running on Fedora C3.
# /usr/local/apache/bin/apachectl start
/usr/local/apache/bin/apachectl: line 65: 9846 Segmentation fault
$HTTPD -k $ARGV
# /usr/local/apache/bin/httpd
Segmentation fault
# /usr/local/apache/bin/httpd -X -f /usr/local/apache/conf/httpd.conf
Segmentation fault
This happens regardless if I have a httpd.conf at all so I'm guessing
it's not a config file issue.
There's nothing in the logs because I don't think it gets that far.
Below is a strace- it looks like it might be missing some apr* library
although I see an apr folder in the source, and I'm guessing it should
have built and installed those.
Can someone who knows about this stuff please give me a clue? Thanks!
Here's some output from gdb, Looks like it failed 'registering hooks' I
also wish I knew what it meant:
