Unexpected dead of the executable in UNIX

[johnyang]

Dear All,

Does anybody know what may cause the following problem?

Problem:

The application become no response. The frequency of the occurrence is about one out of five. The dead point is various every time. I can only know the problem seems more easily come up when the application is busying handle a lot of multi-thread tasks, timer services and interrupt services. When I use “ctrl-c” to terminate the dead application, no core-dump or error message come up. So, it is hard to use GDB or some other debug tools to trace the problem.

About the application:

The application was built out as below:

……

/cc/bts/pde/gnutools/gnu295/sun56/bin/g++    -o /cc/bts/map/card/xcem192/bin/xcem192off/xcem192ap140ych.offtarget   /cc/bts/map/card/xcem192/domain/base/lib/xcem192off/libbase.lnk  /cc/bts/map/card/xcem192/domain/mw/lib/xcem192off/libmw.lnk  /cc/bts/map/card/xcem192/domain/callp/lib/xcem192off/libcallp.lnk  /cc/bts/map/card/xcem192/domain/oam/lib/xcem192off/liboam.lnk  /cc/bts/map/card/xcem192/domain/base/lib/xcem192off/libbase.lnk  /cc/bts/map/card/xcem192/domain/mw/lib/xcem192off/libmw.lnk  /cc/bts/map/card/xcem192/domain/callp/lib/xcem192off/libcallp.lnk  /cc/bts/map/card/xcem192/domain/oam/lib/xcem192off/liboam.lnk  /cc/bts/map/card/xcem192/domain/base/lib/xcem192off/libbase.lnk  /cc/bts/map/card/xcem192/domain/mw/lib/xcem192off/libmw.lnk  /cc/bts/map/card/xcem192/domain/callp/lib/xcem192off/libcallp.lnk  /cc/bts/map/card/xcem192/domain/oam/lib/xcem192off/liboam.lnk   /cc/bts/map/card/xcem192/domain/base/lib/xcem192off/libbase.lnk  /cc/bts/map/card/xcem192/domain/mw/lib/xcem192off/libmw.lnk  /cc/bts/map/card/xcem192/domain/callp/lib/xcem192off/libcallp.lnk  /cc/bts/map/card/xcem192/domain/oam/lib/xcem192off/liboam.lnk       -lsocket -lnsl -lposix4 -lpthread -lm -lstdc++;

This application uses a lot of sun4-solaris pthread library functions and socket functions to simulator a multi-threads environment. I suspect maybe it is caused by a bug of solaris library. So, has anybody ever met such problem before? Your suggestions and directions are welcome!

Looking forward to your response!

Best Regards,
