Phil, There are multiple possible reasons for encountering the out of memory error, other than the main jvm heap, including hitting the ceiling on the Permanent Generation heap or encountering "Unable to create new native thread", etc.
It might be helpful to post a log snippet starting a few entries before to a few entries later, to see the context and detail of the error (if any). That sometimes points to what the actual source might be. You can also enable JRun metrics in the jrun.xml file which will log memory utilization. Additionally, you can prepare for taking a stack trace (or three) at the time that the server is unresponsive. That will enable you to see the thread pool and which pages are running and their state. By taking several thread dumps over a brief period (during the hang) you can compare them to see what's been processed and what's hung. JRun metrics and stack trace generation are easily Googlable for details of usage. If you're still stuck, sometimes JVM Garbage Collection logging is helpful. -- Steven Erat Webapper Services On Mon, May 4, 2009 at 12:19 PM, Phil Fenstermacher < phillip.fenstermac...@gmail.com> wrote: > > I'm running CFMX7 on a server, and we're trying to avoid upgrading to CF8 > since we're actually trying to move away from CF. > > The server was running for weeks at a time with no issues, until recently. > After a reboot (because of a Kernel upgrade for RHEL) it started acting up. > > Roughly every 12 hours, the cfmx7 process becomes unresponsive, and takes > up about 100% of the CPU.
