Thank you for a problem report. Please, try to: telnet 10.0.0.1 3306 and send the results you got. Please, send also the my.cnf file content and the last part of the error log, having that stack trace inside.

Hello, when I try to connect with telnet the result is returned after a few seconds, not immendiatelly - maybe this information helps you. =================================================================== Telnet: =================================================================== Trying 10.0.0.1...

Version: '5.0.18' socket: '/var/mysql5/mysql.sock' port: 3306 Source distribution mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=8388608 read_buffer_size=258048 max_used_connections=1 max_connections=100 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 84591 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x843a2c0 Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... Cannot determine thread, fp=0xbf5ff478, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x80ced92 0x825db40 0xb758ae66 0xb757a21f 0xb757a2dd 0xb7646f9a 0xb76480b7 0x828f719 0x828f480 0x80d5294 0x80ee9a1 0x82585e7 0x828d0da New value of fp=(nil) failed sanity check, terminating stack trace! Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved stack trace is much more helpful in diagnosing the problem, so please do resolve it Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd->query at (nil) is invalid pointer thd->thread_id=2 The manual page at http://www.mysql.com/doc/en/Crashing.html contains information that should help you find out what is causing the crash.

Sorry for a long delay with this report. I do not know how to repeat the behaviour you described. Please, try to install newer version of MySQL, 5.0.20a (our binaries, please), and connect to to it remotely. Inform about the results.
