This is Geronimo 1.1.1 running on Window (!!!) JDK 1.5.0_11 - there *was* Apache running mod_jk but I took it out of the loop using ProxyPass/ProxyPassReverse. There are a small handful of apps (one EAR, maybe 3 WARs) on the server.
We're starting to monitor memory usage more closely, but after the problem occurs, we can't see memory usage - we get that "Not Yet Available" message. _____ From: Peter Petersson [mailto:[EMAIL PROTECTED] Sent: Thursday, July 19, 2007 11:15 AM To: [email protected] Subject: Re: Strange memory problems / white screens Someone is probably going to as you this so I might as well ;) What version of Geronimo are you running ? What jdk version? Is there a Apache server involved via mod_jk ? Is it one G deployed application in particular that you notice the problem in? Is there other G deployed apps? At my work we run a G v1.1.1 server and have several Geronimo deployed applications with occasionally somewhat heavy load without any memory leaks in G (months of uptime) so if this is the version you are using I would start looking at the deployed applications memory handling. Is there a steady increase of memory usage? you can look at the Information page to keep track at it. If this is the case some of your deployed applications may leak memory as the garbage collector cant release some resources (like open database connections holding on to it), tailing good logging output could help locating the problem. regards Peter Petersson Ian Hunter wrote: We've noticed a problem where intermittently Geronimo starts failing to respond to web requests (browser symptom is a blank white screen) - when this starts happening, we notice that on the system info tab, the memory metrics display "Not Yet Available" but after we restart Geronimo completely, web requests work and the memory values display. Has anyone else seen anything like this? _______________________________ Ian Hunter Solution Architect 925 Northpoint Parkway, Suite 430 Alpharetta, GA 30005 678.990.7416 office 770.754.4264 fax 404.314.8693 mobile
