LOW ON THREADS

When Bamboo runs for some time (lets say 10 builds) it hangs repdroducbily directly after a build. The sympton is, that no one can connect to
the webapp anymore, blocking for ever. After 8 minutes or so, the following appears in atlassian-bamboo.log:

2007-02-23 14:47:10,603 INFO [BAM:Default Queue:BuildExe] [SaveBuildTask] Indexing build results...

....

and so on.

A restart is the only workaround for the moment
