httpd segfault

[Jameson]

I recently upgrade a server that was running Fedora 10 with no
problems to Fedora 11.  Now Apache segfaults repeatedly, and won't
respond to requests.  I'm having some trouble tracking down what the
cause is.

My error log repeats:  [Sun Jul 12 14:59:23 2009] [notice] child pid
14784 exit signal Segmentation fault (11)

I've tried running strace httpd -X, and get a lot of output that ends with:

open("/etc/httpd/alias/secmod.db", O_RDONLY) = 42
fcntl64(42, F_SETFD, FD_CLOEXEC)        = 0
read(42, "\0\6\25a\0\0\0\2\0\0\4\322\0\0\20\0\0\0\0\f\0\0\1\0\0\0\1\0\0\0\0\10\0
"..., 260) = 260
lseek(42, 0, SEEK_END)                  = 16384
lseek(42, 4096, SEEK_SET)               = 4096
read(42, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...

lseek(42, 0, SEEK_END)                  = 16384
lseek(42, 8192, SEEK_SET)               = 8192
read(42, "\4\0\344\17\324\16\312\16z\16l\16z\16\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\
0\0\0"..., 4096) = 4096
close(42)                               = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

Does this indicate a problem with the secmod.db file?  Does anyone
know where I should go from here?

Thanks,
