I'm having this issue with our own software built on 14.04.

Attaching to a process, I can't progress. Only detaching allows the
process to process.

The message is

(gdb) break MysqlConnection::change_db_name(std::string const&) 
Breakpoint 1 at 0x9326b7: file /home/.../xxxx.cpp, line 61.
(gdb) c
Continuing.

Title:
  gdb constantly stops with a message "debugger service failed"

Status in gdb package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: gdb

  I'm trying to debug a Firefox plugin. GDB makes it very difficult: it constantly stops debugging, and displays an error message:
  [Thread 0x46f2a950 (LWP 25316) exited]
  Cannot get thread event message: debugger service failed

  If I type "continue", it resumes - only to stop a few seconds later.

  (I had gdb attached while filing this bug report; it stopped seven
  times.)
