I forgot to paste the Falcon configurations. --skip_innodb \ --default_storage_engine=Falcon \ --falcon_io_threads=5 \ --falcon_record_memory_max=650M \ --falcon_page_cache_size=1650M \ --falcon_page_size=4096 \ --falcon_serial_log_buffers=100 \

Xuekun, can you please retry with --falcon_page_size=8k and see whether you get the same assertion?

Also, please try latest Falcon from BZR. We fixed this assertion lately Error: assertion (idx->offset == 0 || (idx->offset >= indexEnd && idx->offset + idx->length <= dbb->pageSize)) failed at line 87 in file DataPage.cpp https://code.launchpad.net/~mysql/mysql-server/mysql-6.0-falcon

Hakan, I tried the latest code. Falcon still crash. But sometimes the assertion were at diffenet place. And sometimes recovery succeeded, sometimes recovery failed. I also tried different falcon_page_size (4k, 8k, 16k), crash as same. The assertion could be [Falcon] Error: assertion (key - (UCHAR*) indexNode < 14) failed at line 109 in file IndexNode.h or [Falcon] Error: assertion (offset + length <= MAX_PHYSICAL_KEY_LENGTH) failed at line 148 in file IndexNode.h ... mysqld: my_new.cc:50: int __cxa_pure_virtual(): Assertion `"Pure virtual method called." == "Aborted"' failed. And sometimes Falcon can identify the below query cause its crash. select c_id from customer where c_w_id = 1 and c_d_id = 2 and c_last = 'ABLEABLEOUGHT' order by c_first asc limit 1 or select c_id from customer where c_w_id = 1 and c_d_id = 4 and c_last = 'PRESCALLYCALLY' order by c_first asc limit 1; And recovery failed at /home/mysql/mysql/libexec/mysqld(my_print_stacktrace+0x2e)[0x9b47ce] /home/mysql/mysql/libexec/mysqld(handle_segfault+0x33b)[0x60b16b] /lib64/libpthread.so.0[0x2b868e137e70] /lib64/libpthread.so.0(raise+0x2d)[0x2b868e137d4d] /home/mysql/mysql/libexec/mysqld(_ZN5Error5errorEPKcz+0xef)[0x82e5bf] /home/mysql/mysql/libexec/mysqld(_ZN5Cache9fetchPageEP3Dbbi8PageType8LockType+0xf5)[0x80de45] /home/mysql/mysql/libexec/mysqld(_ZN3Dbb11handoffPageEP3Bdbi8PageType8LockType+0x2a)[0x825fca] /home/mysql/mysql/libexec/mysqld(_ZN13IndexRootPage17findInsertionLeafEP3DbbiP8IndexKeyij+0xbe)[0x83b27e] /home/mysql/mysql/libexec/mysqld(_ZN13IndexRootPage13addIndexEntryEP3DbbiP8IndexKeyij+0x6f)[0x83b56f] /home/mysql/mysql/libexec/mysqld(_ZN13IndexRootPage10indexMergeEP3DbbiP14SRLUpdateIndexj+0x4dd)[0x83c61d] /home/mysql/mysql/libexec/mysqld(_ZN9SerialLog7recoverEv+0x496)[0x875546] /home/mysql/mysql/libexec/mysqld(_ZN8Database12openDatabaseEPKc+0xf6)[0x821296] /home/mysql/mysql/libexec/mysqld(_ZN10Connection11getDatabaseEPKcS1_P7Threads+0xcc)[0x815b3c] /home/mysql/mysql/libexec/mysqld(_ZN10Connection12openDatabaseEPKcS1_S1_S1_S1_P7Threads+0xa7)[0x8184a7] /home/mysql/mysql/libexec/mysqld(_ZN15StorageDatabase17getOpenConnectionEv+0x58)[0x7e2c08] /home/mysql/mysql/libexec/mysqld(_ZN14StorageHandler10initializeEv+0x99)[0x7e5d19] /home/mysql/mysql/libexec/mysqld(_ZN16StorageInterface11falcon_initEPv+0x159)[0x7ddb19] /home/mysql/mysql/libexec/mysqld(_Z24ha_initialize_handlertonP13st_plugin_int+0x38)[0x6fe198] /home/mysql/mysql/libexec/mysqld[0x7795fa] /home/mysql/mysql/libexec/mysqld(_Z11plugin_initPiPPci+0x8c9)[0x77c0e9] /home/mysql/mysql/libexec/mysqld[0x60f42f] /home/mysql/mysql/libexec/mysqld(main+0x805)[0x610535] /lib64/libc.so.6(__libc_start_main+0xf4)[0x2b868f5668b4] /home/mysql/mysql/libexec/mysqld(__gxx_personality_v0+0x271)[0x548c79] [Falcon] Error: page 131238/1 wrong page type, expected 5 got 7 Thx, Xuekun

Verified based on the ltest tests by Xuekun. Ann, one of these asserts is the same as Bug#38130.

Ann, The first crash is a duplicate of Bug#38130. The second is during recovery after that. If the recovery problem is directly due to 38130, then this can be marked as a duplicate.

Hakan, this one has been on the shelf for a while. Can you re-verify that this occurs, and if so, which call stack is the problem?

And It is interesting to compare with and without SP of DBT2 performance.
