Hi there. My name is Dino Ciuffetti, I'm a linux sysadmin and I'm new to this list.
I have a sporadic problem with mod_jk (tomcat connectors), I hope someone can help me on this. I have Apache/2.2.15 (Unix) mod_jk/1.2.37 PHP/5.3.3 Apache, and PHP are installed via RPM (centos packages), while mod_jk was compiled from source. I have sporadic "segmentation fault" and "stack smashing detected" errors on my error_log: [Mon May 26 11:03:31 2014] [notice] child pid 59191 exit signal Segmentation fault (11) [Mon May 26 11:03:36 2014] [notice] child pid 57331 exit signal Segmentation fault (11) *** stack smashing detected ***: /usr/sbin/httpd.worker terminated ======= Backtrace: ========= /lib64/libc.so.6(__fortify_fail+0x37)[0x7fa19ef57507] /lib64/libc.so.6(__fortify_fail+0x0)[0x7fa19ef574d0] /etc/httpd/modules/mod_jk.so(jk_open_socket+0xa3e)[0x7fa19bd0796e] /etc/httpd/modules/mod_jk.so(ajp_connect_to_endpoint+0x65)[0x7fa19bd25405] /etc/httpd/modules/mod_jk.so(+0x32900)[0x7fa19bd25900] /etc/httpd/modules/mod_jk.so(+0x35952)[0x7fa19bd28952] /etc/httpd/modules/mod_jk.so(+0x1f96a)[0x7fa19bd1296a] /etc/httpd/modules/mod_jk.so(+0xd869)[0x7fa19bd00869] /usr/sbin/httpd.worker(ap_run_handler+0x70)[0x7fa1a0945530] /usr/sbin/httpd.worker(ap_invoke_handler+0xce)[0x7fa1a0948dee] /usr/sbin/httpd.worker(ap_process_request+0x1c0)[0x7fa1a09541f0] /usr/sbin/httpd.worker(+0x38068)[0x7fa1a0951068] /usr/sbin/httpd.worker(ap_run_process_connection+0x68)[0x7fa1a094d038] /usr/sbin/httpd.worker(+0x40f02)[0x7fa1a0959f02] /lib64/libpthread.so.0(+0x7851)[0x7fa19f1ef851] /lib64/libc.so.6(clone+0x6d)[0x7fa19ef3d90d] Reading the backtrace, it seems to me that there is something with jk_open_socket() that is causing the "stack smashing" protection check to fire. We have those errors only on high loads. Anyone have something similar? I cannot find fixed bugs like this on newer versions (bugzilla).
