系统停止响应并引发yami I / O错误

Question

I need suggestion about YAMI library . I have a system which receives Json string from external interface and parse that received string and send that message to internal ip address for the required action. The exchange of messages within the internal ip address has been taken care by Yami library. everything works fine but occasionally it displays yam i/o error and system doesn't response unless it is restarted. The whole software is written in C++ and C and development os is fedora 11.

I have tried to investigate the problem but I am bit clueless as I have not found much help on internet and my testing method doesn't work.

its strange that system works for few hours and then crash . For example If I leave system idle for half an hour and then try to send message via external interface it crashes producing yami i/o error or even while sending continuos command it crashes.

Any help or suggestion will be of great help.

Thanks and regards,
Sam

It looks like this exception is from a core::io_error result which is translated to a runtime exception by details::translate_result_to_exception() . Most of this error originates from the source code in yami/posix in your case.

What you have to do now is figure out where the error originates and ultimately the source of the issue. You should be able to get a rough idea from what happens in your code when the error occurs (are you creating a new connection, sending data, receiving data, etc...).

If that doesn't yield any obvious results I would probably create a test project using the yami source code instead of the library file so I would be able to trace into the yami code to where the error originates from.
