Hi Alchemi Developers, we use alchemi grid application since 1 year. Sometimes we have a problem with executors.
We use Alchemi 1.0.5 with in memory database. If the manager and 2 executors runs about 2 days we notice an exception in the executor. This exception concerns a GThread. The GThread crashes and calculate not to the end. This execption seems to occur randomly. In the executor i can found the following exception message: ... 2007-03-02 18:51:20,656 [ExecuteThreadInAppDomain-thread] WARN - grid thread # 7e0ba4ec-51e3-4a0f-ac74-99492e9d732f.1 failed (System.InvalidOperationException) System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
