Damn! Yesterday evening I leave my internal web server up and running. This morning I experienced a down, so I did some quickly check and I saw that Apache is down. Restarting I read this error message: /usr/sbin/httpd: symbol lookup error: /usr/sbin/httpd: undefined symbol: apr_array_ma+e
I am not sure why it's printing a "+" instead of a "k,", but that symbol should actually be apr_array_make, which is defined in libapr.so: $ nm libapr-0.so.0.9.12 | grep apr_array_make [718] | 48020| 60|FUNC |GLOB |0 |10 |apr_array_make Does the web server hang or does it exit? Do you see any errors in the error_log? Are logfiles rotated around the time of the hang? Do you see the apr_array_make symbol in libapr when the hang occurs? Depending on the type of hang, you should be able to use mod_backtrace (and possibly kill -s SIGABRT) to get a stack trace when the server crashes. If you're interested in using mod_backtrace to debug the hang, I documented how to use it in my Apache internals and debugging presentation, which is on my website: http://prefetch.net Thanks, - Ryan -- UNIX Administrator http://prefetch.net _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
