Here's some more relevant info regarding the reason for the LDM dumping core. Note the log message: > > May 09 14:44:59 5Q:tornado stokes[416515]: Growing data by 3522560 This message is from the queue (not a decoder). When the queue is growing and pqexpire is running, it dumps core. Solution: make the queue larger. Note: currently the queue is allowed to grow only on SGI machines.
