I have a strange apache issue , and I wonder if anyone has seen this before.
I am running Apache 1.3.34 on freeBSD 7.3-RELEASE amd64 . At some
point in the day apache's children segfault and die. No core files are
generated. I am
not running mod_php either.
1. I have setup the following sysctls
#Debug options
kern.sugid_coredump=1
kern.corefile="/var/coredumps/%U-%N-%P.core"
2. The httpd.conf is set with CoreDumpDirectory /var/coredumps/
3. The dir /var/coredumps/ is set 1777
4. A ktrace of the parrent apache process shows the core file tries to create
84954 libhttpd.ep RET kill 0
84954 libhttpd.ep CALL sigreturn(0x7ffffffeb030)
84954 libhttpd.ep RET sigreturn JUSTRETURN
84954 libhttpd.ep PSIG SIGSEGV SIG_DFL
84954 libhttpd.ep NAMI ""/var/coredumps/65534-libhttpd.ep-84954.core""
34924 libhttpd.ep RET select 0
34924 libhttpd.ep CALL gettimeofday(0x7fffffffe890,0)
34924 libhttpd.ep RET gettimeofday 0
34924 libhttpd.ep CALL fork
5. I have proc mounted and I can't gcore -s $PID either
I have no cores and I am stumped .
