Thank you for the report. But version 5.1.28 is a bit old. Please try current version 5.1.30 and if problem still exists provide more information about your machine: how much physical RAM it has, OS version, MySQL configuration file. Would be good if you could run debug version (mysqld-debug) and get core file.

I have upgrade the MySQL to 5.1.30, but it still crash after a few days. The err message is: /usr/local/mysql/libexec/mysqld(my_print_stacktrace+0x2e)[0x837bde] /usr/local/mysql/libexec/mysqld(handle_segfault+0x322)[0x5976f2] /lib64/libpthread.so.0[0x3f1700de80] /usr/local/mysql/libexec/mysqld(_Z12mysql_selectP3THDPPP4ItemP10TABLE_LISTjR4ListIS1_ES2_jP8st_orderSB_S2_SB_yP13select_resultP18st_select_lex_unitP13st_select_lex+0x570)[0x6184b0] /usr/local/mysql/libexec/mysqld(_Z13handle_selectP3THDP6st_lexP13select_resultm+0x169)[0x618a09] /usr/local/mysql/libexec/mysqld[0x5a1cec] /usr/local/mysql/libexec/mysqld(_Z21mysql_execute_commandP3THD+0x1807)[0x5a7197] 081207 13:08:33 - mysqld got signal 11 ; This could be because you hit a bug.

Thank you for the feedback. Could you please try to locate query which causes crash? You can do it in 2 ways: 1. Run mysqld-debug instead of mysqld and get core file, then send us both core file and mysqld-debug file. 2. More difficult way if you can not run mysqld-debug, for example, because performance reason. Enable query logging (probably general log could help, but even better if you do it at application level), then locate query which fails. Thanks in advance.
