I've delved into this. The perl script that is 'mysqlhotbackup' does the following:
.. and thus it locks it (from my experience) for read only. So I'm testing with: while :; do sleep $[ $RANDOM / 8192 ]; rcmysql stop; rcmysql start; done This tends to tickle things. I've run 'gdb ./radiusd' then '(gdb) run -f' and I am at the following prompt: [New Thread 31776 (LWP 27266)] Delayed SIGSTOP caught for LWP 27266. LWP 26565 exited. Cannot find thread 33: invalid thread handle (gdb) tr trace command requires an argument (gdb) bt #0 0x401c0931 in __linuxthreads_create_event () from /lib/libpthread.so.0 #1 0x401ba3bb in pthread_handle_create () from /lib/libpthread.so.0 #2 0x401b9d2d in __pthread_manager () from /lib/libpthread.so.0 #3 0x401b9e3d in __pthread_manager_event () from /lib/libpthread.so.0 (gdb) This doesn't look very familiar to me, perhaps I am in some other thread's context and not the place where the problem occurred? -- Todd Fries ..
