Does it happen every > time? How many VCPUs are there? At boot time, Tomcat is not running, so I start Tomcat and I have this error. Then I can't do anything, the system is "locked". It happens every time I start Tomcat with any java runtime which is not java-gcj on Debian Lenny or Etch. There are 4 VCPUs on each Tomcat. > > > Jul 31 21:24:15 tomcat01 kernel: 1 multicall(s) failed: cpu 3 > > Jul 31 21:24:15 tomcat01 kernel: call 1/1: op=14 arg=[b7f1a000] > result=-22 > > Jul 31 21:24:15 tomcat01 kernel: ------------[ cut here ]------------ > > Jul 31 21:24:15 tomcat01 kernel: kernel BUG at > arch/x86/xen/multicalls.c:103! > > Jul 31 21:24:15 tomcat01 kernel: invalid opcode: 0000 [#1] SMP > > Jul 31 21:24:15 tomcat01 kernel: > > Jul 31 21:24:15 tomcat01 kernel: Pid: 2467, comm: jsvc Not tainted > (2.6.25.7 #1) > > Jul 31 21:24:15 tomcat01 kernel: EIP: 0061:[<c020248b>] EFLAGS: > 00010202 CPU: 3 > > Jul 31 21:24:15 tomcat01 kernel: EIP is at xen_mc_flush+0x16b/0x180 > > Jul 31 21:24:15 tomcat01 kernel: EAX: 00000000 EBX: 00000000 ECX: > 00000003 EDX: 00000000 > > Jul 31 21:24:15 tomcat01 kernel: ESI: 00000000 EDI: 00000001 EBP: > c141a060 ESP: deaadedc > > Jul 31 21:24:15 tomcat01 kernel: DS: 007b ES: 007b FS: 00d8 GS: 0033 > SS: 0069 > > Jul 31 21:24:15 tomcat01 kernel: Process jsvc (pid: 2467, ti=deaac000 > task=df6e6000 task.ti=deaac000) > > Jul 31 21:24:15 tomcat01 kernel: Stack: c05a5848 00000001 00000001 > 0000000e b7f1a000 ffffffea 00000200 00000065 > > Jul 31 21:24:15 tomcat01 kernel: 00000000 00000000 b7f1a000 > c02592b4 00000065 00000000 df5c3f50 00000000 > > Jul 31 21:24:15 tomcat01 kernel: 000b7f1a 00000000 00000000 > de827e34 df616210 de827e00 b7f1b000 df616528 > > Jul 31 21:24:15 tomcat01 kernel: Call Trace: > > Jul 31 21:24:15 tomcat01 kernel: [<c02592b4>] > mprotect_fixup+0x4b4/0x610 > > Jul 31 21:24:15 tomcat01 kernel: [<c0259554>] > sys_mprotect+0x144/0x1d0 > > Jul 31 21:24:15 tomcat01 kernel: [<c0206c22>] syscall_call+0x7/0xb > > Jul 31 21:24:15 tomcat01 kernel: ======================= > > Jul 31 21:24:15 tomcat01 kernel: Code: 00 83 c3 20 89 54 24 08 89 74 > 24 04 c7 04 24 48 58 5a c0 89 44 24 0c e8 84 fc 01 00 8b 95 00 0b 00 00 > 39 d6 72 c3 e9 25 ff ff ff <0f> 0b eb fe 0f 0b eb fe 8d b6 00 00 00 00 > 8d bc 27 00 00 00 00 > > Jul 31 21:24:15 tomcat01 kernel: EIP: [<c020248b>] > xen_mc_flush+0x16b/0x180 SS:ESP 0069:deaadedc > > Jul 31 21:24:15 tomcat01 kernel: ---[ end trace 9edfe58cbc53ddca ]--- > > > > > > Do you get any messages on the Xen console (xm dmesg)? xm dmesg (complete dmesg) : (XEN) Xen version 3.2.1 (root@xxxxxxx) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) Mon Apr 28 09:51:46 CEST 2008 (XEN) Latest ChangeSet: Fri Apr 25 14:03:45 2008 +0100 16881:4073b3ded545 (XEN) Command line: auto BOOT_IMAGE=Xen ro root=801 (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: none; EDID transfer time: 0 seconds (XEN) EDID info not retrieved because no DDC retrieval method detected (XEN) Disc information: (XEN) Found 1 MBR signatures (XEN) Found 1 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 000000000008f000 (usable) (XEN) 000000000008f000 - 00000000000a0000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 00000000cf543000 (usable) (XEN) 00000000cf543000 - 00000000cf54f000 (reserved) (XEN) 00000000cf54f000 - 00000000cf617000 (usable) (XEN) 00000000cf617000 - 00000000cf6e8000 (ACPI NVS) (XEN) 00000000cf6e8000 - 00000000cf6eb000 (usable) (XEN) 00000000cf6eb000 - 00000000cf6f0000 (ACPI data) (XEN) 00000000cf6f0000 - 00000000cf6f1000 (usable) (XEN) 00000000cf6f1000 - 00000000cf6ff000 (ACPI data) (XEN) 00000000cf6ff000 - 00000000cf700000 (usable) (XEN) 00000000cf700000 - 00000000d0000000 (reserved) (XEN) 00000000fff00000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 0000000230000000 (usable) (XEN) System RAM: 8181MB (8377980kB) (XEN) Xen heap: 14MB (14824kB) (XEN) Domain heap initialised: DMA width 32 bits (XEN) Processor #0 7:7 APIC version 20 (XEN) Processor #2 7:7 APIC version 20 (XEN) Processor #1 7:7 APIC version 20 (XEN) Processor #3 7:7 APIC version 20 (XEN) IOAPIC[0]: apic_id 2, version 32, address 0xfec00000, GSI 0-23 (XEN) Enabling APIC mode: Flat.
