selvaganesang opened a new pull request #1795: [TRAFODION-3260] SSMP may wait 3 seconds before
handling requests
URL: https://github.com/apache/trafodion/pull/1795
 
 
   Encapsulated the changes in the commit 2ee272b325d021 to Ipc layer.
   
   [TRAFODION-3274] At times sqlci or any other SQL process fails to come up and dumps core
   
   It looks like there is a race condition in C++ main function prologue while
   initializing the embedded global objects and the stdin, stdout and stderr file
   descriptors.
   
   File descriptor of value 2 is returned for epoll_create(). But, the error redirection
   code possibly used this fd to redirect overriding the epoll fd.
   
   This caused epoll_ctl to return EINVAL resulting in core dump of sql process.
   
   Changed the global object gv_sock_ctlr to a global object pointer.
