Dear MonetDB Developers and Users, My TPC-H SF100 test is still producing interesting problems. After several hours of work I have managed to import near 420 million record to the lineitem table (7x 60 million record slice). Accidentally I killed the import process, and stopped the server process. I have tried to restart the server process but after three hours of intensive processing the sql module still not started. Please note that the initialization process allocated nearly all memory and swap. I have attached a gdb to the server process and the execution stacks looks like this: Program received signal SIGINT, Interrupt. 0x00002b240cb1c2a4 in file_read () from /usr/lib/libstream.so.0 (gdb) where #0 0x00002b240cb1c2a4 in file_read () from /usr/lib/libstream.so.0 #1 0x00002b240cb1b744 in stream_readLngArray () from /usr/lib/libstream.so.0 #2 0x00002b240c67a27f in lngRead () from /usr/lib/libbat.so.0 #3 0x00002b240c788e90 in logger_readlog () from /usr/lib/libbat.so.0 #4 0x00002b240c789b0c in logger_create () from /usr/lib/libbat.so.0 #5 0x00002aaaaab42658 in store_init () from /usr/lib/MonetDB5/lib/lib_sql.so #6 0x00002aaaaab179b3 in mvc_init () from /usr/lib/MonetDB5/lib/lib_sql.so #7 0x00002aaaaaacf9f4 in SQLinit () from /usr/lib/MonetDB5/lib/lib_sql.so #8 0x00002b240bf89e3a in initScenario () from /usr/lib/libmal.so.0 #9 0x00002aaaaaacf968 in SQLsession () from /usr/lib/MonetDB5/lib/lib_sql.so #10 0x00002b240bf6536e in runMALsequence () from /usr/lib/libmal.so.0 #11 0x00002b240bf6697b in runMAL () from /usr/lib/libmal.so.0 #12 0x00002b240bf5f3f3 in MALengine () from /usr/lib/libmal.so.0 #13 0x00002b240bf5e3ab in callString () from /usr/lib/libmal.so.0 #14 0x0000000000402a65 in main () (gdb) c Continuing.
