Hey list, when I set SSLSessionCache to shm:/opt/apache/logs/ssl_scache(512000) or to shmcb:/opt/apache/logs/ssl_scache(512000) httpd childs dump core with this output to the error_log when LogLevel is set to debug : [Mon Mar 19 08:45:27 2007] [info] Initial (No.1) HTTPS request received for child 2 (server www.example.com:443) [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(468): [client 10.1.2.3] inside shmcb_status [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(983): entering shmcb_expire_division [Mon Mar 19 08:45:27 2007] [debug] ssl_scache_shmcb.c(535): [client 10.16.250.8] leaving shmcb_status [Mon Mar 19 08:45:27 2007] [info] [client 10.1.2.3] Connection closed to child 2 with unclean shutdown (server www.example .com:443) [Mon Mar 19 08:45:28 2007] [notice] child pid 27827 exit signal Bus error (10), possible coredump in /opt/apache When running ipcs -sa to display shared memory usage as root, I get no output. With my old apache 1.3 using mod_ssl and MM I have output when running ipcs -sa To fix my problem, I have set SSLSessionCache to use dbm, that way I get no errors but it is documented that dbm can suffer instability under heavy load ... Anyone can help fixing this ? any suggestions ? I built apache with Sun Studio 11 under Solaris 8 with mod_authnz_ldap/openldap in 64bit with these flags to the compiler -fast -xarch=v9b -xcode=pic32 , I then compiled mod_perl and mod_evasive using apxs Thank you Yannick ______________________________________________________________________ Apache Interface to OpenSSL (mod_ssl) www.modssl.org User Support Mailing List [email protected] Automated List Manager [email protected]
