Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: John van Schie (johnvanschie) Assigned to: Nobody/Anonymous (nobody) Summary: Mserver sends no response, client hangs. Initial Comment: We are using MonetDB4, Feb2009-SP2, build from source (build log attached) with 64bit OIDS. The platform is Fedora core 10, with 64 GB RAM (55GB cached) and 99GB free disk space for the dbfarm. Our application uses mclient to manipulate XML in the database. This morning, I saw a mclient process that did not terminate and is still running after approx. 12 hours. Using strace on the mclient process shows that the process is waiting for blocking I/O. Executing a fresh mclient with the query "1+1" results in a stalled application, that also waits for blocking I/O. (see attached strace). It seems that Mserver stopped sending data to the clients. To debug this problem, I've generated stack traces of all threads for the Mserver and a list of open files (lsof). The server is still running, and I plan to keep it running unless no more information is needed. Unfortunately, the server is build with optimisation enabled and cannot share the data, as it is confidential. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2801629&group_id=56967 ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
