I thought things like memory allocation would depend on the kernel (or glibc malloc?) - host kernel is 2.6.13.1

Not tried it yet, but I found this which may be of interest - literally thousands of these stacktraces in the logs. I believe the interface that pcap was bound to was restarted - but I am not sure this is the cause. After that the interface refuses to be brought back up (inside the guest), only a guest reboot does it, and dmesg has this message too: [43003437.440000] dev_ip_addr - device not assigned an IP address [43003437.440000] pcap_dispatch failed - recvfrom: Network is down Here is the repeated message: [42977981.360000] Badness in local_bh_enable at kernel/softirq.c:140 [42977981.360000] a037f6c0: [<a001c4de>] dump_stack+0x1e/0x20 [42977981.360000] a037f6e0: [<a0053fcc>] local_bh_enable+0x6c/0x90 [42977981.360000] a037f710: [<a0230caa>] __dev_remove_pack+0x7a/0xa0 [42977981.360000] a037f720: [<a0293b93>] packet_notifier+0xd3/0x130 [42977981.360000] a037f750: [<a005df9e>] notifier_call_chain+0x1e/0x40 [42977981.360000] a037f780: [<a0231689>] dev_close+0x89/0xa0 [42977981.360000] a037f7b0: [<a0039058>] uml_net_interrupt+0x68/0x70 [42977981.360000] a037f7d0: [<a006e006>] handle_IRQ_event+0x36/0x90 [42977981.360000] a037f800: [<a006e0fc>] __do_IRQ+0x9c/0xf0 [42977981.360000] a037f820: [<a0016fdf>] do_IRQ+0x2f/0x40 [42977981.360000] a037f830: [<a0017534>] sigio_handler+0xd4/0x110 [42977981.360000] a037f860: [<a0023c78>] sig_handler_common_skas +0xa8/0x130 [42977981.360000] a037f890: [<a0040b9f>] sig_handler+0x2f/0x40 [42977981.360000] a037f8b0: [<ffffe420>] ifaddrs+0x5fa477e0/0x4 [42977981.360000] a037fbb0: [<a0019a3a>] default_idle+0x5a/0x80 [42977981.360000] a037fbe0: [<a0023724>] init_idle_skas+0x24/0x30 [42977981.360000] a037fbf0: [<a00015d1>] start_kernel+0x181/0x1c0 [42977981.360000] a037fc00: [<a002375b>] start_kernel_proc+0x2b/0x30 [42977981.360000] a037fc10: [<a00194bf>] run_kernel_thread+0x2f/0x40 [42977981.360000] a037fcd0: [<a0023401>] new_thread_handler+0xb1/0x110 [42977981.360000] a037fd20: [<ffffe420>] ifaddrs+0x5fa477e0/0x4 [42977981.360000] Another query, unrelated (I think): what does this mean? [42949410.920000] uml_net_start_xmit: failed(-1) Last, is it possible that there is a connection leak in the socket code? I've experienced problems running tomcat and ntop in uml guests (but not apache...), after a while the process are still running but do not respond to SYN packets, although netstat and lsof still list the processes as listening on the port - I think I'll prepare a root_fs instance for you to try out. The problem with ntop could be linked with the example above of the interface disappearing for a short while, and as for Java it could be many things..
