RE: java.lang.OutOfMemoryError: unable to create new native thread
We had out-of-memory problems with CFMX 6.1 udpater, and using metrics determined it wasn't growing the heap as it was supposed to. (We've stuck with the same settings on CFMX 7). I'd try starting the heap at the same size as the maximum, and also experiment with starting the Permanent Generation at 256, ... and get those metrics going. Here's a simple thing you can use in the interim: cfset runtime = CreateObject(java,java.lang.Runtime).getRuntime() !--- change amount from bytes to MB --- cfset freeMemory = runtime.freeMemory() / 1024 / 1024 cfset totalMemory = runtime.totalMemory() / 1024 / 1024 cfset maxMemory = runtime.maxMemory() / 1024 / 1024 cfoutput Free Allocated Memory: #Round(freeMemory)# MBbr Total Memory Allocated: #Round(totalMemory)# MBbr Max Memory Available to JVM: #Round(maxMemory)# MBbr /cfoutput br !--- From these numbers we can also determine the percent of free allocated memory available, and also the percent of avalaible memory allocated --- cfset percentFreeAllocated = Round((freeMemory / totalMemory) * 100) cfset percentAllocated = Round((totalMemory / maxMemory ) * 100) cfoutput % of Free Allocated Memory: #percentFreeAllocated#%br % of Available Memory Allocated: #percentAllocated#%br /cfoutput -- Original Message -- From: Russ [EMAIL PROTECTED] Reply-To: cf-talk@houseoffusion.com Date: Tue, 11 Apr 2006 12:16:02 -0400 I have already played with those settings, but it still crashed yesterday.

Re: java.lang.OutOfMemoryError: unable to create new native thread
have you turned on metrics logging? Maybe you need to up your max sim threads. your error trace has quite abit about JDBC in it. Are you limiting your DSN connections?

take a look at these blogs too http://www.robisen.com/index.cfm?mode=entryentry=39E0B0C6-55DC-F2B1-FBBDB70CEC963D6D http://www.bpurcell.org/blog/index.cfm?mode=entryentry=967 http://www.petefreitag.com/item/89.cfm I'd turn your metrics logs on right away, use these to help you adjust the above. http://www.macromedia.com/cfusion/knowledgebase/index.cfm?id=tn_19120 If you format the log outputs right, you can load up the data into Excel and play BA, generating purt graphs and all.
