UPDATE:things improved dramatically for us after I did a clean recompile of DSpace, making sure to use the right version of Java. ;-)
We still had masses of errors showing in the tomcat log, as before, but tomcat at least did not fall over every five minutes. In fact, it remained up all day. (But mysteriously crashed sometime last night.) This morning, I restarted with the setting "db.statementpool = false" in dspace.cfg, and this has resulted in the "Timeout waiting for idle object" messages disappearing entirely through all of this morning. We had a a reappearance of this error starting at 12:30pm and eventually tomcat required a restart an hour later. So ... problem not really solved, but DSpace is now as stable as it was on 1.3.2, so I guess we call that progress.:-) Steve Steve Thomas wrote: > I found a thread on dspace-tech about this (typically unresolved) with > the suggestion to tweak the db.maxconnections and db.maxidle parameters. > > So ... changed db.maxconnection from 30 to 50, and db.maxidle from -1 to 5. > > Also changed maxconnections in postgresql.conf from 100 to 150. > > Unfortunately, this has made no difference. :-( > > Steve > > > > Steve Thomas wrote: >> More problems following the 1.4.2 upgrade: >> >> We're getting heaps of errors from tomcat, like this: >> >> 17/03/2008 13:05:14 org.apache.catalina.core.StandardWrapperValve invoke >> SEVERE: Servlet.service() for servlet mydspace threw exception >> java.util.NoSuchElementException: Timeout waiting for idle object >> >> The "manual" suggests restarting postgresql to fix this, but that worked >> only for a few minutes.
