10094 Warning: invalid file descriptor 1028 in syscall close 10094 Warning: invalid file descriptor 1029 in syscall close Linux 10093 10093 HEAP SUMMARY: 10093 in use at exit: 861,318 bytes in 5,903 blocks 10093 total heap usage: 71,738 allocs, 65,835 frees, 10,611,196 bytes allocated 10093 10093 LEAK SUMMARY. Valgrind is an “instrumentation framework for building dynamic analysis tools”, according to Valgrind’s official documentation. Valgrind comes with a bunch of tools, but in this page we will only focus on one of those tools: Memcheck. 6168 Warning: invalid file descriptor 1019 in syscall socket 6168 Warning: invalid file descriptor 1019 in syscall open 6168 Warning: invalid file descriptor 1019 in syscall open. For each of those requests, valgrind reports the warnings shown above but doesn't report the 'invalid. This shows up as a Valgrind warning 18197 Warning: invalid file descriptor -1 in syscall close 18197 at 0x5F6E5BD:??? (syscall-template.S:84) 18197. MARS maintains file descriptors internally and allocates them starting with 3. File descriptors 0, 1 and 2 are always open for: reading from standard input, writing to standard output, and writing to standard error, respectively (new in release 4.3).

Valgrind Invalid File Descriptor In Syscall Close Command
The reason is that THD::disconnect is getting called twice, once from server thread-killing thread:
kill_server_threads -> kill_server -> close_connections -> close_connection -> THD::disconnect;
and the second time from the query thread itself, as in the above stacktrace.
