In the /proc/meminfo output I see that the system has 16 GB RAM and 33
GB swap memory. Also, MemFree + Buffers = 400 KB, which makes me
assume the system was under heavy memory pressure ?

Some essential information is still missing - the reason why the
kernel started spewing out all these call traces. Did someone hit the
SysRq key ? Is it because a task was hanging ? Was a BUG or WARNING
hit ?

Bart.
