[Sqlrelay-discussion] [run time error] accessing mysql db using SQL relay & c++ ( linux, mysql, rudiments, sqlrelay)

[<jh...@ha...>]

Hi

 

I am working on setting up an multithreaded application with below os &
library.

 

OS: linux fc3

Compiler: gcc 3.4.2 20041017

Mysql-4.1.15

Rudiments-0.28.2

Sqlrelay-0.36.4

 

For stress test. Concurrent 50 transaction loop 1000000 count.

One day after, our application abnormal terminationtion with dump.

50 x 2856 transaction succeded.

 

Below, gdb bactrace result.

Any ideas? Whats it looking for?

 

Thanks!
