[Valgrind-users] Valgrind/Epoll issue

[Austin E. <aus...@gm...>]

Hi
I have  a typical issue while using valgrind with epoll stuff.

I have ubuntu 14.04 system.
I have implemented epoll client server code.

When I execute epoll client and servers without valgrind, I see a proper
communication between epoll client and server.

When I execute epoll client with valgrind and epoll server (without
valgrind),  I see there is no communication between epoll client and
server.

On debugging found that epoll out events does not come for client sockets.

Is it a known valgrind issue?
Or I am missing something.

Thanks
Austin

To my knowledge, there is no problem with epoll and Valgrind.
What version are you using ? On which platform ?

To understand what is going on, you might:
  1. start Valgrind with  --trace-syscalls=yes
and/or
  2. debug your program under Valgrind, using option --vgdb-error=0
