Various errors in glu's log

[rantav]

I went through glu's logs and have seen a number of errors which I don't know what to correlate them to. So I thought it wouldn't hurt to share the log files and open a generic bug report which later could be refined to more specific bugs. My hope is that maybe you'd see something that can easily be fixed without further investigation b/c I don't have, for any of the reported errors in the files, any specific repro, I just saw them in the logs when looking back. Please see this gist https://gist.github.com/1131599 for a sample of two complete error log files taken from our production setup. Many of the errors repeat, I didn't uniq them. Hope this will helps
