[otrs] OTRS 2.2b3 on Win XP Pro: Apache crashes when attaching big file

Hi all, when I try to append a rather big attachment, e.g. 17MB, Apache causes the page file to grow until it crashes with a memory fault. However, with a smaller attachment, e.g. 5MB, there is no crash but the file is not appended either. Therefore, I have tried to modify the value of MySQL variable "max_allow_packet" for testing purposes but it did not help. However, I do not know how to determine if my change has been accepted at all. Furthermore, in a second attempt, I have set option "Kernel::System::Ticket::ArticleStorageFS" in ticket.xml, but it did not remove the malfunction either. Do I something wrong or is this strange behavior a bug? Kind regards Branislav Dobrodolac
