RE: java.lang.OutOfMemoryError after server app start/stop cyclin g
Type java -X in a windows shell and look at setting some of the below options in your environment using JAVA_OPTS -Xmssizeset initial Java heap size -Xmxsizeset maximum Java heap size -Xsssizeset java thread stack size I alse use this to allocate more memory to ant at build time for a large application. 'set ANT_OPTS=-Xmx512m' (in a .bat) or pop it in your environment profile.

RE: java.lang.OutOfMemoryError after server app start/stop cyclin g
Haven't done it myself but I thought you had to edit the registry to modify VM settings for a TC service. See if there's a TC entry at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services Quoting Daniel Perry [EMAIL PROTECTED]: eh? i thought ANT_OPTS was for ant, not tomcat. I dont have any trouble with ant using default memory allowance. Its tomcat that is running out of memory, and is ignoring the CATALINA_OPTS.
