After some fiddling, got cores turned on for the threaded client tend and they all tend look like this. #0 0x0075c7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 (gdb) where #0 0x0075c7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x007a17a5 in raise () from /lib/tls/libc.so.6 #2 0x007a3209 in abort () from /lib/tls/libc.so.6 #3 0x0079ad91 in __assert_fail () from /lib/tls/libc.so.6 #4 0x08076773 in io_datafile_complete_operations () #5 0x0806dcef in PINT_client_state_machine_testsome () #6 0x08056537 in process_vfs_requests () #7 0x08058a2a in main () This is the actual assert pvfs2-client-core: src/client/sysint/sys-io.sm:1860: io_post_write_ack_recv: Assertion `ret == 0' failed. Also I'm not quite sure why I'm not seeing error messages (that I'd expect) in the client log _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
