-Condor uses clone in a way that causes GDB grief. Running a Condor daemon under GDB will likely fail with errors similar to: - -{code} -warning: Can't attach LWP -1: No such process -../../gdb/linux-thread-db.c:389: internal-error: thread_get_info_callback: Assertion `inout->thread_info != NULL' failed. -A problem internal to GDB has been detected, -further debugging may prove unreliable. -Quit this debugging session? (y or n) -{endcode} - -The solution is to tell Condor to not to use clone, but to fall back on the fork code path. In your Condor configuration file, use: - -{code} -USE_CLONE_TO_CREATE_PROCESSES = false -{endcode} - -(This page primarily exists as search bait, so that others hitting this error can quickly find the solution.) - -For the adventurous (or those who are debugging the clone calls), one can apply the patch found on #2208 +This content was moved to DaemonDebugging. Look for "clone".
