Hi all, I am facing an occasional VPP crash from dead_client_scan() when I restart a client . I am using VPP version v18.01.1-100~g3a6948c. Upgrading to a newer version is not an option for me currently.
Here is the backtrace : Program terminated with signal 6, Aborted. *#0 0x00002ad10a37f207 in raise () from /lib64/libc.so.6* *Missing separate debuginfos, use: debuginfo-install OPWVmepCR-99.9-el7.x86_64* *(gdb) bt* *#0 0x00002ad10a37f207 in raise () from /lib64/libc.so.6* *#1 0x00002ad10a3808f8 in abort () from /lib64/libc.so.6* *#2 0x0000000000405ef3 in os_panic () at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vpp/vnet/main.c:268* *#3 0x00002ad1097fb6d2 in clib_mem_alloc_aligned_at_offset (os_out_of_memory_on_failure=1, align_offset=<optimized out>, align=4, size=60)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/mem.h:105* *#4 vec_resize_allocate_memory (v=<optimized out>, length_increment=length_increment@entry=4, data_bytes=<optimized out>, header_bytes=<optimized out>, header_bytes@entry=0, data_align=data_align@entry=4)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/vec.c:84* *#5 0x00002ad1097bd5bc in _vec_resize (data_align=0, header_bytes=0, data_bytes=<optimized out>, length_increment=4, v=<optimized out>)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/vec.h:142* *#6 format_integer (s=<optimized out>, s@entry=0x308d6a84 "svm_client_scan_this_region_nolock:", number=<optimized out>, options=options@entry=0x2ad10d3cabf0)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/format.c:535* *#7 0x00002ad1097be32e in do_percent (va=0x2ad10d3cac78, fmt=<optimized out>, _s=<synthetic pointer>)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/format.c:314* *#8 va_format (s=0x308d6a84 "svm_client_scan_this_region_nolock:", fmt=<optimized out>, va=va@entry=0x2ad10d3cac78)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/format.c:404* *#9 0x00002ad1097bd707 in format (s=<optimized out>, fmt=fmt@entry=0x2ad10980b5a3 "%wd:")* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/format.c:423* *#10 0x00002ad1097b9234 in _clib_error (how_to_die=how_to_die@entry=4, function_name=function_name@entry=0x2ad10959a0a0 <__FUNCTION__.11526> "svm_client_scan_this_region_nolock", line_number=line_number@entry=1205, * * fmt=fmt@entry=0x2ad10959a00f "%s: cleanup ghost pid %d") at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/error.c:122* *#11 0x00002ad109586b11 in svm_client_scan_this_region_nolock (rp=0x30021000) at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/svm/svm.c:1204* *#12 0x00002ad10820b896 in dead_client_scan (am=<optimized out>, now=<optimized out>, shm=0x3004300c)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vlibmemory/memory_vlib.c:803* *#13 memclnt_process (vm=0x2ad1086af260 <vlib_global_main>, node=0x2ad10d3c2000, f=<optimized out>)* * at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vlibmemory/memory_vlib.c:1091* *#14 0x00002ad10845b656 in vlib_process_bootstrap (_a=<optimized out>) at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vlib/main.c:1231* *#15 0x00002ad1097c6838 in clib_calljmp () at /bfs-build/build-area.44/builds/LinuxNBngp_mainline_RH7/2018-10-18-1026/third-party/vpp/vpp_1801/build-data/../src/vppinfra/longjmp.S:110* *#16 0x00002ad10d249e30 in ??
