Hi, My brand new sparkling OpenBSD VPS is currently in crisis. Unfortunately there is no reset function to it and I forgot to set the "break to ddb" function. The vps admin staff is probably already asleep so I'll have to wait a few hours. On console it says repeatedly:
pagedaemon: wait_pla deadlock detected! I have tracked it down to this function in uvm/uvm_pmemrange.c ----- int uvm_wait_pla(paddr_t low, paddr_t high, paddr_t size, int failok) { struct uvm_pmalloc pma; const char *wmsg = "pmrwait"; if (curproc == uvm.pagedaemon_proc) { /* * XXX detect pagedaemon deadlock - see comment in * uvm_wait(), as this is exactly the same issue. */ printf("pagedaemon: wait_pla deadlock detected!\n"); msleep(&uvmexp.free, &uvm.fpageqlock, PVM, wmsg, hz >> 3); #if defined(DEBUG) /* DEBUG: panic so we can debug it */ panic("wait_pla pagedaemon deadlock"); #endif return 0; } ----- Now while the opportunist in me says "we should really panic here" instead of having a DEBUG kernel, the realist in me says to hold on and think of others. The question for me then is is the wait_pla pagedaemon deadlock situation recoverable, or is this really a bug? Hoping some kernel developers will pick this up and move it to tech@ if that's appropriate! I wish I had a dmesg for you but I didn't save one offline from this vps. I can tell you this much. It's virtualbox'ed, has 2 cpu's and since yesterday has some memory intensive application that may cause some things to be moved to swap. I'm gonna have to see to reduce the memory on that I guess.
