Greetings. I am trying to get the semantic role labeler running. I think I have got everything compiled and configured properly, but when I try to process a single, simple tokenized sentence, it hangs at some point along the way. It appears from the log files (contents below) that all of the components with logs are working as they should. The problem seems to be in the bin/beamsearch/search executable.
As you can see from the top iteration captures (below the log contents, showing only processes using CPU to save space) at the second iteration several srl components are running and a zombie appears. By the next iteration, search, fex, and snow are running. By the last it’s just search, consuming almost all of one cpu (out of two). It sits there like that ad infinitum. If I kill the process holding search, inference.pl comes to the top, runs for a while, then the job ends with no output. The /tmp/2127.result file mentioned in the srlservercental log is filled with several thousand lines that say: double beam!!
Anyone have a suggestion for what might be wrong, or how to debug?
Cheers,
Steve
