Hello , mans
Your server have a bug that sometimes cause coredumps.....
System: FreeBSD 4.2-20001127-STABLE
Compiler: gcc 2.95.2
Platform: x86 (PII-600)
Ram: 256 Mb
With server work only one program - IServerd, there is 10 parallel
processes that have db connection.
Here information that i get from cores
