Gdb produces error messages: Attaching to program: /usr/sbin/jabberd, process 23634 Couldn\'t get registers: Operation not permitted. A program is being debugged already. Kill it? (y or n) n Program not killed. If then I try to kill the process with \'kill\' command, gdb hangs. An attempt to quit gdb produces the following dialog: (gdb) quit The program is running. Quit anyway (and detach it)?

You cannot ptrace some processes now which were praceable before. There are no solution yet, 2.4.21 won\'t be released untill this problem gets fixed. And gdb is innocent. You may want to reassign this bug to kernel package. 8842 2 ldv 2003-04-13 00:35:22 +0400 This is a 2.4.20-alt7 problem, known side effect of kmod ptrace fix.
