This bug isn't my top priority now. So, If there is volunteer, I'm willing to give up this bug. :) Do you want to fix this bug ? 1028424 5 ryuan.choi 2014-08-11 22:34:13 -0700 I traced the bad fd and it looks because g_main_context_query returns bad fd which is already closed. I reproduced it as clicking "reload" button frequently on the MiniBrowser (which loads google.com) And when select (in ecore_glib.c) is failed, one of fd which returns g_main_context_query got EBADF. In strace, I got below log.

It seems something is broken near the websocket implementation, which caused the test flakiness, and I assume the non-working inspector server is related to this bug too - https://bugs.webkit.org/show_bug.cgi?id=125073 1286192 7 mcatanzaro 2017-03-11 10:32:47 -0800 Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
