The web server crashed, this is also a 4-CPU SS-10, equipped with Ross RTK-625 Hypersparc CPU's, 384MB of RAM, CGSIX video, no other additional hardware.
This machine is running completely stock Linux 2.2.13, which is to say I have not applied ANY patches to this kernel at all.
It was compiled with:
gcc -v Reading specs from /usr/lib/gcc-lib/sparc-redhat-linux/egcs-2.90.29/specs gcc version egcs-2.90.29 980515 (egcs-1.0.3 release)
After running approximately 9 hours, it crashed with the following on the console:
spin_lock_irqsave(eeb2066c) CPU#0 stuck at f00cb048, owner PC(00000000):CPU(1) spin_lock(f0153994) CPU#1 stuck at f002dea4, owner PC(f004a44c):CPU(0) [...repeat same two lines....]
Relevant addresses: First line:
eeb2066c Nothing close in System.map:
00000000 A ___s_user_ptrs_per_pgd effff000 A ___h_stack_top__btset_0xeffff000 f0000000 A ___h_page_offset__btset_0xf0000000
Perhaps this was something on the stack?
f00cb0048 Between the following two:
f00cb018 T rpc_clnt_sigunmask f00cb0ac T rpc_do_call
... would this mean something in function rpc_clnt_sigunmask()?
And then why is PC(00000000) all zeros?
Second line:
f0153994 Between the following two:
f0153908 D smp_proc_in_lock f0153988 D boot_cpu_id
f002dea4 Between the following two:
f002de08 T patchme_store_new_current f002e150 T __wake_up
f004a44c Between these two:
f004a428 T sys_writev f004a560 T sys_pread
