All, Updates to this issue....
-I'm not sure if it's the OS, but I've never seen this happen before on other Solaris installs. What would I look at to determine if it's the OS?.. The way that question is phrased makes it difficult for me to completely understand what you mean. Can you be more specific? -It did take up memory until Tomcat would no longer serve pages. Users would try to see their sites and just get a blank white screen until their request timed out. I haven't let it time go incrementally since I've upgraded Tomcat or the jdk, however, I may let it stall out if I get that desperate. -I upgraded to 1.4.2 and still the memory increases. -Yes, I'm closing all streams in the email class. Also, this particular code has been used successfully across platforms and across java servers for about 3 years now. Anymore input is greatly appreciated. -Seth. ----- Original Message ----- From: "Nikolaos Giannopoulos" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Friday, September 12, 2003 6:04 PM Subject: RE: Memory Leak with static content > Seth, > > Have you tried JDK 1.4.2? 1.4.0 has been known to have a memory leak in the > StringBuffer implementation w.r.t. re-using StringBuffers but you mention > that your only serving static content so this may not be it. > > However, I believe that I read that something like 2000 bugs have been fixed > in 1.4.2 (if my memory serves me well).
