How can I correlate "merge phase X" messages in the logs with a specific process?
We have been seeing messages like this during periods where Vertica is responding particularly slowly: 2013-05-26 09:01:38.816 nameless:0x2aab3caa78c0 [EE] Beginning intermediate merge phase 1: 346 buffers to merge in increments of 19. The session IDs for these events don't seem to correspond to anything else. Are these tuple mover events? Is there any way to determine which specific processes these messages are being generated by?
