------- Additional Comments From trawick@apache.org  2003-08-05 14:18 -------
The portion of the backtrace showing idle server maintenance ran in the parent
process prior to fork()-ing this child.

This backtrace is from the child.  The backtrace is for the main thread of the
child, which sits in read() until the parent tells it to go away.

Either we don't have the backtrace for the thread that segfaulted (> 99.99%
chance) or Solaris read() is broken.  read() is responsible for returning EFAULT
if passed an invalid buffer, so this backtrace isn't consistent with any likely
segfault.

See what other backtraces are in the coredump.  Also, the Solaris pflags program
often identifies the thread that segfaulted.
