FW: SIGSEGV SEGV_MAPERR

[Apologies, I may have sent this before from the wrong mail-box]


Hello
         I am running the Blastwave packaging of Freeradius 1.0.1 on Solaris
8, sparc. 
This interfaces with MySQL version 4.0.18-log, built from source.
 
The RADIUS server inexplicably terminates with no core dump or logged
messages
 
The tail of a truss log shows
bash-2.05# grep SEGV_MAPERR truss.log | wc -l
   1766
bash-2.05# tail -20 truss.log

10471/1:        978.8140        _exit(1)

 
It got into a SEGV_MAPERR 1766 times while I had it under truss...
 
This error is superficially similar to the one reported by Terry J Fike Jr
in July 2004, but here the server exits voluntarily.
 
Has this problem been encountered before?
What further investigation should I do?
 
                                                        Thank you,
                                                                  Barry
