I heard back from the machine's admin. The time of the crash I observed
matches exactly to these events in the kernel log:
May 07 03:31:39 gcc202 kernel: dm-0: writeback error on inode 2148294407,
offset 0, sector 159239256
May 07 03:31:39 gcc202 kernel: sunvdc: vdc_tx_trigger() failure, err=-11
May 07 03:31:39 gcc202 kernel: blk_update_request: I/O error, dev vdiskc,
sector 157618896 op 0x1:(WRITE) flags 0x4800 phys_seg 16 prio class 0
So it's not a mirage. The admin seems to think it might be a kernel
bug though.
