Hi all, We just moved Mendix into the new (bigger server) which is a 64-bits environment (Windows Server 2008 and Java). The major reason to set everything 64-bits, becausewe have to increase the Java heap space to 2GB or higher. Our users of this system produce more than 600 Excel files per day (not a standard Mendix excel export). Everything went so far pretty well, except that we have notice that the server sometime crash without showing error in the log. Here is the remarkable symptom, that 2 of 8 core of our CPU consume 100% of usage before it crash, while other 6 core run under 10% of usage. The memory looks find, no java heap space at all. Do you think that this may caused by JDK 64-bit version? Does anyone has this kind of remarkable symptom with the 64-bits environment? Or suggestions what could be wrong configured? Many thanks, Panayu
Does the windows event log show any entry during these crash periods?
@Hans: I have checked the windows event log, but there seems to be very normal.
Here is more details about the server. See the remarkable CPU peak in the attached image.
