This happens at least for the Meta-GP engines of pspitzli. The cause for this is still unclear. Investigate!

Worked on stability of plugin-infrastructure (uncaught exceptions in an AppDomain brought down the whole process) in changesets:

r241: exception-handling in main-app and graceful unloading of faulted AppDomains
r242: automatic restart of 'service' applications
r243: grid-client and grid-server are service applications and should be restarted automatically.

Worked on stability and reliability of the grid-infrastructure and the distributed-engine. See changesets:

r240: grid-server GUI improvment
r244: graceful shutdown of grid-client
r254 (#150): re-queuing unfinished jobs at the server
r246: bug-fixes related to r244
r247: deleted unused interface-class related to r244
r248: improvement of stability and reliability on the client-side. introduction of job-manager class that is responsible for sending jobs to the server and receiving results. distributed-engine only has to process results from the job-manager.
r249: bugfix for incorrect sleeping-intervals, related to r248
r250 (#140): grid-server GUI improvment
r251: stability improvement of grid-client
r252: another bugfix related to r251
r253: client-side stability-improvement
r254: improved memory-footprint server-side (removed caching of old results)
r255: minor change
r256: fixed client-side memory-leak introduced with r248
r257: improve client-side memory-footprint, removed caching of serialized zipped engines for restarting jobs.
r258: minor change, sleep first then try to fetch result.
