My mid-tier is on tomcat 5.5.26 on Win2K3 Ent x64, so this may not translate well, but I have had the best results with initial/maximum of 1536mb/1536mb and thread stack size 3000. ITSM is a pig. Now that I have production users in mid-tier, peak memory usage for this tomcat instance is 951mb (right now; in testing it was seldom over 600mb).

We're running IM 7.03, SLM 7.1 on ARS 7.1. We are getting the typical java.lang.OutOfMemoryError: Java heap space errors - obviously we need to increase it. We are in a large environment and we're running dedicated Solaris mid-tier servers (ie, no Email Engine to compete for Java resources on this box). The default websphere settings for heap size are 50mb/256mb min/max. The only thing on these boxes is the mid-tier so we don't have to worry about memory usage beyond what we are doing. What is everyone else setting theirs to? I'm thinking 256mb/1GB min/max might be a good starting point but feedback would be appreciated. Thanks in advance.
