#79 multiply ss5 instances run several hours,then suddenly terniate with segfault.

Hi,
I run multiply ss5 instances and they worked fine for several hours,then many of them suddenly terniate with segfault.
Do you have any idea?

Kindly regards
James

Hello,

you should run:

gdb ss5 (including path) and core file (including path). Attach the output.

Bye
