Can you pull the vdiattr branch and try again? Hi Kazutaka. I pulled the vdiattr branch, did a make clean && make, and then retested using that. The first 4MB chunk uploaded successfully, and then the second caused collie to segfault: [4707] collie vdi write d5e2e937-2a25-415b-b9e0-ec931ff64c43 8388608 4728 Segmentation fault (core dumped) collie vdi write d5e2e937-2a25-415b-b9e0-ec931ff64c43 8388608 Exit code: 139 This is (gdb) bt #0 0x00007f95f654ed38 in memset () from /lib/libc.so.6 #1 0x000000000040536d in vdi_write (argc=<value optimized out>, argv=<value optimized out>) at vdi.c:1141 #2 0x0000000000402543 in main (argc=5, argv=0x7fff4194d2c8) at collie.c:343 which is /* exit after this buffer is sent */ memset(buf + (len - remain), 0, remain); I can reproduce this fairly reliably with 0026# dd if=/dev/zero bs=1k count=4096 | collie vdi write d5e2e937-2a25-415b-b9e0-ec931ff64c43 8388608 4096+0 records in 4096+0 records out 4194304 bytes (4.2 MB) copied, 0.211225 s, 19.9 MB/s Segmentation fault (core dumped) Cheers, Chris. |
